摘要
通过实验研究氯离子对CODcr测定的干扰程度,采用硫酸汞掩蔽法、氯离子扣除法、稀释倍数法等方法去除氯离子的干扰,最终确定出处理的最佳方案是在不掩蔽氯离子条件下,对水样中氯离子产生的CODcr值进行扣除,且实验证明此种方法对实际水样同样适用。方法适用氯离子范围为0～8000mg/l。
This work has been carried out to study the interference of chloride ion in Chemical Oxygen Demand determinations under different conditions. Several methods (mask chloride ion by the addition of mercuric sulfate , silver nitrate deposition, subtracting chloride ion ,dilution etc) have been investigated. The result shows this is the best method of removing chloride ion available for most wastewater samples.
