摘要：Nitrate salts are used widely in many areas as fertilizers in agriculture, explosives, oxidizing agents inthe chemical industries, and as food preservatives especially to cure meats. If the range of nitrates increases inenvironment shows many dangerous and ill effects. Conversion of nitrate was needed. In this study TSS, TDS, BOD,COD and 93 % highest conversion of nitrate was found from the optimized conditions. The final form of the proposedmodel equation for the percentage conversion of nitrate was Ys=0.93(1-e-0.698t). Where Ys = percentage conversion ofnitrate and t= conversion time (hr).The model showed good agreement with experimental data by generating averageabsolute relative deviation (AARD) of about 0.92± 2.9% conversion of nitrate from steel industry effluent usingmembrane separation process.
