生活垃圾全磷测定消解过程中酸用量的选择

Dosage of Acid during Digestion in Determination of Total Phosphorus from Domestic Waste

通过实验确定使用硫酸-高氯酸消解体系消解生活垃圾样品中磷时的硫酸和高氯酸的最佳用量,结果表明:消解0.5 g左右的垃圾样品,硫酸和高氯酸的最佳用量分别为2.0、1.5 mL。

The optimal dosage of sulphuric acid and perchloric acid for digesting phosphorus from domestic waste was determined by using sulphuric acid and perchloric acid digestion experiments. The results showed that the optimal dosage of sulphuric acid and perchloric acid was 2. 0 mL and 1.5 mL respectively, when about 0. 5 g domestic waste was digested.
