Treatment of Sulfide Group in Sediments of Gas Bottle Household by Using Green Copper Nanoparticles of Coriandrum sativum L. Extracts
The study included treatment of sulfide group which the main contaminate in sediments in gas bottle household by sorption on the surface of Coriandrum sativum L copper nanoparticles using column chromatogaraphy techniq and surface absorbtion. The high surface area of nanoparticles means that even weak sorption of contaminants to surfaces can introduce a significant new pathway for exposure or removal of molecular contaminants as well as we using green synthesis to prepare nanoparticales which give more safety when used it to removal the contaminants especially sulfide group from sediment of gas bottle household. Green synthesis of copper nanoparticles is effective and environmentally friendly technique for the synthesis of nanoparticles. In present study the seeds of Coriandrum sativum L. are used for synthesis of copper nanoparticles (CuNPs) that's formed by using an aqueous solution of CuSO4•5H2O (2mM) with the seed aqueous extracts of Coriandrum s. as reducing and stabilizing agents, and the change of color solution assures the formation of copper nanoparticles. UV-Visible scanning revealed qualitative formation of CuNPs and characteristic absorption peak in the range of 400-500 nm. The optimization of the different conditions, including temperature, time, pH, concentration of copper sulfate pentagonal water CuSO4•5H2O and the mixing ratios of reactants to prepare the copper nanoparticles (CuNPs) were studied also. The optimal condition for the installation of copper nanoparticles revealed that the concentration of copper sulfate pentagonal water was 2mM, temperature 70 C°, and pH was 9.8, incubation time 30 min. The results of absorb of sulfide group in sediments of gas bottle household in both methods indicated the effectivity of copper nanoparticles for removal of this group, then this sediment become safety for environment
