Preparation of cation exchange resin of carrying ferrum and its ability of removing residual chlorine from drinking water
This paper described the method of D40l cation exchange resin was modified through ion exchanging in Fe2+ soln. According to this modified resin with the property of that the redox of Fe2+ and chlorine, and achieving the aim of removing the minim content of residual chlorine from the water. The experiments indicate that when the concentration of Fe2+ solution was 4045.44 mg/L, reaction 2 h and the pH value between 3 and 5. In this way the iron content in the resin was 39.648 mg/g. The efficiency of removing chlorine could reach above 98% and the residual chlorine in the water was below 0.5 mg/L. In addition, this method do not bring other ions into the water. A new remarkable method of remove the nocuous residual chlorine from the drinking water was got.
