Spectrophotometric Determination of Chloride Ion in Molybdenum Chemical Wastewater
The determination of chloride ion content in molybdenum chemical wastewater by spectrophotometry is in-troduced,and the best detection conditions are determined.Under the selected experimental conditions,the working curve of chloride ion is y =0.001 1x-0.000 5,and the correlation coefficient is R2 = 0.999 8.The detection limit is 0.033 mg/L,the relative standard deviations are 2.55%and 2.66%,and the recovery rate is 93.75%～108.33%.This method has the advantages of simplicity,rapidity,good precision and high accuracy,it can also meet the needs of daily production and detection.
