针对硫酸酸解含磷废弃物产生的含磷酸解液,采用不同的氧化剂氧化酸浸液,再根据沉淀剂的理论加入量,推算最佳沉淀剂用量,可有效测定出多种酸浸液中的磷含量。结果表明,高锰酸钾的氧化效果最好;1 m L喹钼柠酮沉淀剂可有效沉淀P_2O_5 0.6~0.8 mg;加入柠檬酸、丙酮可有效消除元素干扰。该法操作简单,结果准确,具有一定应用价值。
Aiming at the phosphoric acid-containing liquid produced by the sulfuric acid solution phosphorus-containing waste, different oxidants are used to oxidize the acid soaking liquid, and then the optimal precipitating agent dosage is deduced according to the theoretical addition amount of the precipitating agent, Of phosphorus content. The results showed that the oxidation of potassium permanganate was the best. 1 m L Quimoclnyl precipitant effectively precipitated P_2O_5 0.6 ~ 0.8 mg. The addition of citric acid and acetone could effectively eliminate the element interference. The method is simple, accurate and has certain application value.
