用硝酸与盐酸处理废定影液样品,可将样品中的硫代硫酸络合物与离子完全分解.加入氨水、银和氨生成很稳定的银氨络离子,用原子吸收分光光度法测定废定影液中的银含量.方法的相对标准偏差小于3%,加标回收率96.2%~102.4%.
用硝痠與鹽痠處理廢定影液樣品,可將樣品中的硫代硫痠絡閤物與離子完全分解.加入氨水、銀和氨生成很穩定的銀氨絡離子,用原子吸收分光光度法測定廢定影液中的銀含量.方法的相對標準偏差小于3%,加標迴收率96.2%~102.4%.
용초산여염산처리폐정영액양품,가장양품중적류대류산락합물여리자완전분해.가입안수、은화안생성흔은정적은안락리자,용원자흡수분광광도법측정폐정영액중적은함량.방법적상대표준편차소우3%,가표회수솔96.2%~102.4%.
In this study ,under the treatment of nitric acid and hydrochloric acid ,thiosulfate complex and ion in the waste fixer samples were completely decomposed .The adding of aqueous ammonia ,silver ,and ammonia generated very stable silver ammonia complex ion .To determine silver content in waste fixative , the atomic absorption spectrophotometric method was used .The relative standard deviation of this method was less than 3% and the standard addition recoveries were between 96 .2% -102 .4% .
