摘　　要：低压离子色谱与钼黄法联用,建立了水体中磷酸盐、硅酸盐同时测定的新方法。优化的实验条件下,磷酸盐(以P计)和硅酸盐(以Si计)分别在0.2~6 mg.L-1和0.056~4.2 mg.L-1呈良好线性,检出限分别为0.02 mg.L-1和0.006 mg.L-1,相对标准偏差分别为2.27%和0.32%,加标回收率分别为93.3%~101.0%和93.0%~107.1%。A new method for the simultaneous determination of phosphorus and silicon in water using low press ion chromatography and molybdenum yellow method detected by spectrophotometry was described.Under the optimized conditions,the calibration curves of phosphate and silicate ions were linear in the range of 0.2-6 mg·L-1 as P and 0.056-4.2 mg·L-1 as Si,with a limit of detection of 0.02 mg·L-1 and 0.006 mg·L-1,respectively.Relative standard deviations(RSD) for phosphate and silicate were less than 2.27% and 0.32%,...
