Nanoparticles are usually synthesized from metals, such as silver, gold, platinum, copper and zinc. There are several methods used for the synthesis of nanoparticles, such as physical, chemical and biological. People all over the world use different kinds of personal care products (PCPs), like soaps, sunscreen lotions, hair styling products, hair removers, shampoos, conditioners, moisturizers, anti-agers, nail and cuticle care products, oral care including toothpaste and whiteners. Curry leaves are part of a regular diet in India and many parts of the world, it may also serve as a possible nutritional intervention and the extract itself or fractions obtained there from may be used also as a future nutritional supplement to combat oxidative stress-induced tissue damage in the people exposed to lead. Plant mediated synthesis of silver nanoparticles and the study of their size and properties are of fundamental importance in the advancement of recent research. The size and shape of the nanoparticles form a basis for the wide variety of applications. In the present study, biosynthesis and characterization (UV-visible spectroscopy and FTIR) of green nanoparticles from aqueous extract of curry leaves (Murraya Koenigii) and coriander leaves (Coriandrum sativum) was performed and the same was subjected to adsorption studies for wastewater treatment to find out the optimum pH, dosage and time of action for effective removal. The initial absorbance value of household wastewater was 0.788. After treating with zinc nanoparticle synthesised from curry and coriander leaf extract was found to be 0.422 and 0.615, respectively. In this, Murraya koenigii (curry leaves) proves more efficient for treating household wastewater.
