Abstract

The study was carried out for synthesis of guargum silver iron nanocomposite (GG@Ag-Fe) material by co-precipitation method from guargum polymer GG@ polymer for removal of nitrate pollution in drinking water. The synthesizes material was characterized by using energy dispersive X-ray analysis (EDX), fourier-transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM) analysis and ultra violet (UV) spectroscopic  analysis.The GG@Ag-Fe nanocomposite was proved to be good adsorbent for removal of nitrate pollution  from drinking water.Thus Response Surface Methodology (RSM) four key parameters: dose of the nanocomposite, contact time, pH, and initial nitrate concentration was evaluated for obtaining maximum nitrate degradation was used. The optimal values were achieved for maximum nitrate removal at nanocomposite dose of 1.0 mg/L, a contact time of 10.0 minutes, a pH of 6.0, and an initial nitrate concentration of 60.00 mg/L. Under these conditions, the model predicted a nitrate degradation efficiency of approximately 99.00%, while there was a good degree of match with the quadratic model with an R2 of 0.94, best explained the experimental data. Although the proposed GG@Ag-Fe nanocomposite was produced good results for removal of nitrate pollution from real samples having concentration of 59.5 to 150.4 mg/L by 95 to 96.5%. Moreover the removal of nitrate follows first order kinetics while the   reusability of GG@Ag-Fe nanocomposite 75%was achieved.
