摘要
利用硫离子可选择性渗透通过聚氯乙烯处理过的滤纸的性质,制备了硫离子选择性检测试纸。该试纸测定硫化物溶液具有选择性好和抗干扰能力强的特点,其检测限和线性范围分别为31μmol/L和35-2 100μmol/L。该硫化物分析方法已经成功地应用于磷肥矿渣和河床污泥中硫化物的测定。
The selective test paper for sulfide ion has been prepared utilizing sulfide ion＇s property of selective penetration in the filter paper treated with polyvinyl chloride.The test paper possesses the quality of better selection and improved antiinterference in testing sulfide solution,with a detection limit of 31 μmol/L and the linear range of 35-2 100 μmol/L.This method has been successfully applied to the determination of sulfide in slag phosphorus fertilizer and river sediments.
