732型大孔阳离子交换树脂对铅吸附性能的研究
Study on 732 resin for adsorption of lead
摘要
Abstract
By resin adsorption of lead in solution can rich the lead at low concentration, which is important in the detection of lead in foods. Based on the absorption rate of lead, 732 cation exchange resin was picked up from 732 and D113-type. Ion exchange resin was taken in this paper. And the effects were studied of resin amount, adsorption time, lead concentration, speed, temperature and pH value on adsorption. The results indicated that the adsorption time, temperature, lead concentration and pH value had greater influence. Through the orthogonal experiment, the whole process was optimized i and the resin adsorption of lead in the best conditions for the resin werej quality of 8 g, the concentration of lOmg/L, the exchange temperature of 30"C , pH value of lead of 5. 85, the adsorption time of 3 hours. On this condition t the rate of resin adsorption in lead was up to 94, 5%.关键词
