Experimental Study on Determination of Total Iron in Water by Automatic Discrete Spectrophotometry

Abstract:

A new method was introduced for rapid measurement of iron ions in drinking water by automatic discrete spectrophotometry. In the iron concentration range 0-1.5mg/L, the linear relationship was good and the correlation coefficient was 0.9998. The total iron detection of recovery efficiency was 99.94%±1.6% and detection limit was 0.006mg/L and precision of the RSD% was 0.35%. The results show that the method was direct, fast, stable operation and lower iron concentration in water can be accurately detected.There is no significant difference compared with the results of atomic absorption spectrometry methods.
