摘要
根据FIA梯度稀释技术建立了一种新的标准加入方法,只需要注入一种标准溶液,就能形成浓度梯度。本方法流路简单,使用手动进样阀。使用UV分光光度计,用本法测定标准试样中的铁和锰,取得了满意的结果。每小时可测试60个样品。
Based on the gradient dilution technique of FIA, a new standard addition method is established. Concentration gradient can be formed by injection of only one single standard solution. The flow system is simple and a manual injector is used. The method has been applied to the UV spectrophotometric determination of iron and Manganese in standard samples. The results of the measurement are satisfactory. The sampling rate is 60 samples per hour.
