Bioinorganic chemistry is found as a sizzling field in today’s era. It deals with chemistry amongst the heavy metals with natural resources, i.e., air, soil, water, plant byproducts (foods), and environmental essences. The aim of this research is to determine the concentration of heavy metals present in the food waste water sample and to study the environmental effects of metal ion concentration. To conduct the research work, the physicochemical parameters and levels of five heavy metals of food waste water samples were collected from five sampling points of renowned hotels, restaurants, canteens, and confectionaries of a state of India and assessed using the standard analytical procedure. Sampling was carried out from January 2017 up to December 2017. The physicochemical parameters were determined such as pH, temperature, turbidity, conductivity, total dissolved solids, total suspended solids, total alkalinity, biological oxygen demand, chemical oxygen demand, dissolved oxygen, total organic carbon, sulphate, nitrate, and phosphate. The heavy metal concentration was determined by using the UV-spectrophotometer, and the results were compared with the standards prescribed by the WHO, BIS, ICMR, and municipal authorities. The results obtained in the physicochemical analysis revealed that a few parameters were found beyond limits, and the metal ion concentration (iron and zinc) results were found above the permissible limits set by the CPCB (Central Pollution Control Board), ICMR, BIS, and World Health Organization (WHO), most especially, effluent from point P1. It was concluded that all the effluents required further treatment before releasing them into the water body or land to prevent pollution. The obtained results reveal that waste water used for irrigation and farming of nearby areas and water drained from restaurant kitchens were considerably polluted and not suitable for aquatic organisms, irrigation, and agricultural purposes.

Lipase-catalyzed asymmetric synthesis of ketoprofen was developed by response surface methodology under Box-Behenkon experimental designs. The optimal reaction system was Novozym 435 from Candida Antarctica, 1 -propanol as acyl donors, isooctane as reaction medium, and water content of 0.5%. Optimization of reaction temperature, substrate molar ratio (acyl donors: ketoprofen) and enzyme concentration was carried out response surface methodology under Box-Behenkon experimental designs. Optimal conditions were: temperature 36.62 °C, substrate molar ratio 3.5:1, and enzyme concentration 4.91 g/L. the conversion was 46.68%, eep was 93.35%, and E was 73.8 at optimal conditions. Reaction progress at optimum synthesis conditions showed that very satisfactory conversion (64.74%) and production concentration (20.13 g/L) could be achieved in short time (6 h).

Different immobilized method of CRL to influence on chiral resolution of racemic paroxol was explored. First of all, physical adsorption, covalent attachment and enzymeaggregate coating methods were performed to prepare immobilized enzyme. The immobilization efficiencies of immobilized BCLs by physical adsorption, covalent attachment (CA-BCL-NH2-IL-SBA) and enzyme-aggregate coating methods (EAC-BCL-NH2-IL-SBA) were 69%, 67% and 85%, respectively. CA-BCL-NH2-IL-SBA and EAC-BCL-NH2-IL-SBA possessed higher thermal stability, reusability, storage stability than BCL-NH2-IL-SBA. Lastly, three kinds of different immobilized method to influence on chiral resolution of racemic paroxol were anlysised. The enzyme immobilized by enzyme-aggregate coating showed high ee (95%) and E(78). the physical adsorption showed the high conversion(42%).
