摘要
分别采用活性炭和浓硫酸处理黄磷,研究其脱砷效果,并采用库仑滴定仪对脱砷效果进行检测,结果表明,活性炭脱砷可以采用累积处理的方法,经过三次处理后,黄磷中的砷质量分数由433×10-6降低到143×10-6,总脱砷率达到65.1%;浓硫酸氧化法的脱砷率可以达到60%。
The effects of removing arsenic were studied by using activated carbon and concentrated sulfuric acid to dispose yellow phosphorus respectively,and were measured by adopting coulometric titration instrument.The results showed that arsenic content of yellow phosphorus reduced from 433 ×10-6 to 143 ×10-6 with activated carbon adsorption method,and its total removing arsenic ratio reached 65.1%,whereas the total removing arsenic ratio of concentrated sulfuric acid oxidation method was 60%.
