The composition of phosphorus tail gas is mainly CO (≥ 85%), containing a small amount of CO2, H2, N2, CH4 and other harmful impurities, including phosphide, sulfide, sulfide, arsenide, fluoride, The main form of PH3, H2S in the form of harmful impurities in the accurate quantitative analysis of components for the comprehensive utilization of yellow phosphorus tail gas resources is particularly important.
Tengzhou Xiangying Analytical Technology Co., Ltd. used GC7990 gas chromatography to determine the PH3, H2S in the yellow phosphorus tail gas. The experimental results show that the chromatographic separation is good, the coefficient of variation is less than 19% and the detection limit is 0. 0 2 × 10 - 6, and the detection limit of H2S was 2 × 10 - 6. The quantitative analysis method of PH3
黄磷尾气组成以 CO为主 (≥ 85 % ) ,含少量CO2 、H2 、N2 、CH4 等组分 ,并含微量磷化物、硫化物、砷化物、氟化物等有害杂质 ,其中磷化物、硫化物主要以 PH3、H2 S的形式存在 ,对有害杂质组分的准确定量分析 ,对于综合利用黄磷尾气资源尤为重要。
滕州市翔鹰分析技术有限公司采用GC7990气相色谱法测定黄磷尾气中 PH3、 H2 S的分析方法 ,实验结果表明色谱分离良好 ,精密度重复测定的变异系数≤ 19% ,PH3检测限为 0 .0 2× 10 - 6 ,H2 S定量检测限为 2× 10 - 6 ,重点考察了 PH3定量分析方法
