摘　　要：利用反相流动注射系统，对光泽精－Ｈ２Ｏ２－Ｓｎ（Ⅳ）化学发光新体系进行了研究。考察了测定锡的最佳条件，在选定条件下测定Ｓｎ（Ⅳ）的线性响应浓度为３０×１０－９～９．０×１０－６ｇ／ｍｌ，方法灵敏度较高，检测下限达２５ｎｇ／ｍｌ，对含５．５×１０－７ｇ／ｍｌＳｎ（Ⅳ），ｎ＝１１，ＲＳＤ为３．７％，本法用于沉积物标样中锡的测定，其结果与推荐值吻合。The entitled chemiluminescence system and its optimum reaction condition were studied by using reversed flow injection. Chemiluminescence apparatus were made in the laboratory.The linear range of calibration curve is 3.0×10-9-9.0×10-6g Sn(Ⅳ)/ml and the detection limit is 2.5 ng/ml.The method was applied to the determination of Sn(Ⅳ) in deposit reference samples with satisfactory results.
