The density, M.V., and A.M.V. of copper surfactant derived from fried and unfried sesame and soyabean oils in non-aqueous and non- polar solvent benzene has been determined at constant temperature 298.15 K. Three samples of each oil were taken fresh, after treating at high temperature for 15 minutes and 60 minutes. The results were used to determine to CMC, chain length effect of the surfactant molecule on CMC and solute-solvent interactions. The studies were used to analyze the effect of high temperature treatment on the structure of the oil and molecular changes. The conclusions have been discussed in terms of well-known Massons. This helps us to the use of the oils after abuse of frying at high temperature as they have various industrial and biological applications. Colloidal behavior of copper surfactant used in to study of micellar features and their possible uses in agriculture and industries.

A new series of Substituted-4-Biphenyl-acetamides have been synthesized by condensation of 4-Biphenyl acetic acid with different primary amines (aromatic and aliphatic). 4-Biphenyl Acetic Acid was first treated with Thionyl Chloride in dry benzene to prepare substituted-4-biphenyl acetyl chloride, which is then treated with different aliphatic or aromatic amines to synthesize various substituted-4-biphenyl Acid-amide derivatives. The Structure of newly synthesized compounds has been established by analytical and spectral methods. These all six biphenyl compounds were screened for antimicrobial activity. All compounds at different concentrations were analyzed for antifungal activity via disc diffusion method. The antimicrobial activity was screened against fungus Curvalaria lunata. All six compounds showed moderate to good activity against selected fungal strain. These synthesized compounds have shown Anti-fungal properties when they tested against Curvalaria lunata.

Colloidal and micellar characterization of Cu (II) soap complex solutions in benzene + methanol mixture has been studied and analysed by measuring density and surface tension parameters. This study confirms that CMC values depend upon solvent mixture composition and it is observed that CMC decrease with increase in chain length of copper surfactant (caprylate, caprate and laurate). It has also been affected by the polarity of the solvents as non- polar benzene and polar methanol were taken to analyze this effect. Szyszkowski’s empirical equation has been successfully applied to our referred system and it is found that the change in the behaviour of copper surfactant complex carried out at definite concentrations in different compositions of solvent mixture. It is also observed that the parachore of soaps solution increases with the mole fraction of the copper surfactant complex. The results show that there is justification in applying Hammic and Andrew’s equation to these complex solutions in benzene methanol mixtures.

The waste water treatment techniques such as Activated sludge process, Adsorption/bio-oxidation process, Advanced oxidation process, Aerated lagoon, Aerobic granular reactor, Aerobic granular sludge technology and Phytoremediation, are practised in different industries worldwide. In this study Phytoremediation method is applied to study the waste water quality parameters removal efficiency of different plants for treating waste water. The main objective of the study is to find the efficiency of removal of different waste water quality parameters from the synthetic waste water generated in the laboratory by different plants such as Hyacinth, Vetiver, Pharagmites austrilus, and Canna Indica. The waste water quality parameters such as Total hardness, Biological oxygen demand, Dissolved oxygen, Total dissolved solids, Lead, Zinc and Copper are taken in the synthetic waste water samples preparation. After experimental studies using Phytoremediation models, the results arrived are as follows: (1) Hyacinth removal efficiency from Total hardness synthetic solution  is 69.28% and from total dissolved solids  (TDS) synthetic solution  is 3.35% and also it is observed that the Dissolved oxygen(DO)  and Biological oxygen demand(BOD) reduction from synthetic solutions prepared . (2) Canna Indica removal efficiency from TDS synthetic solution is 2.63% and also it is observed that the DO and BOD demand reduction from synthetic solutions prepared. (3) Vetiver removal efficiency from TDS synthetic solution is 74.92% and also it is observed that the DO and BOD reduction from synthetic solutions prepared. Vetiver removal efficiency from Zinc, Lead and Copper synthetic solutions are 14.43%, 47.61% and 32.07% respectively. Phragmites austrilus removal efficiency from Zinc, Lead and Copper synthetic solutions are 10.67%, 19.07%, and 23.27% respectively.  Since the retention time is less in this study it has come less removal efficiency for different plants. It is observed that the phytoremediation technique is very economical and may be implemented to many industries.

The copper mustard and soyabean surfactants have been synthesize and characterize by IR and NMR spectroscopic techniques. The photo catalytic degradation of copper mustard and soyabean surfactants have been carried out by zinc oxide in non- aqueous solutions. Various factors such as effect of concentration, dose of ZnO, light intensity and solvent polarity were varied to achieve the optimum rate of photo degradation. Both copper surfactants were degraded successfully by using ZnO under UV light. The disappearance of copper surfactants follows a pseudo-first- order kinetics according to the Langmuir–Hinshelwood (L–H) model.

Fe2+ reaction with 1, 10-Phenanthroline determined the quantity of soluble iron (II) in the sample to transform a weakly colored iron into an intensely colored complex which could be used in the analysis. The substance absorbed certain wavelengths when a light from the source with a certain intensity and frequency range was passed to this intensely colored complex. The intensity of a solution’s color is proportional to the absorbing species concentration and the absorption is proportional to the substance concentration. A separate concentration of standards was prepared and absorbance in 511 nm, the largest wavelength, was determined using Colorimeter. Using the same standard technique and reagents, a blank and three unknown samples were also prepared. A calibration curve was built following Beer’s Law. The iron concentration was verified using the equation of the calibration curve and the absorption under the same experimental conditions of three unknowns.
