Interference Study of Phosphates and other impurities affecting the Estimation of Fe2+ions from River Patalganga

The Patalganga River basin is delimited by several steel industries. The expected iron content in the river sample was on the higher side; however, the results acquired were in disparity with the expected values. Hence, it became necessary to carry out a study on interfering radicals in the estimation of Iron from the river samples. Taking into consideration the other industries in the industrial belt, the study was limited to certain impurities only. The masking of iron was studied by varying the conditions of the iron standards using a wide range of impurities like Phosphates and other radicals like Al, Zn, Pb, Cd, and Cu. The results revealed that when the concentrations of Iron and Phosphate are in 1:1 ratio almost 90.39% of the iron was being suppressed.
