| Abstract: | A flow injection spectrophotometric analysis method for on-line determination of Mn2+ in water is proposed,and an automatic on-line Mn2+ in water analyzer was developed based on the principle of potassium periodate spectrophotometry.The experimental conditions have been optimized.The experimental results indicate that the method has higher anti-interference ability,and the Mn2+can be determined in the range of 0.01~10mg/L with the detection limit of 0.017mg/L.The RSD is 1.21% (n=12).The method can be applie... |
