| 摘 要： | 本文研究了皮革铬鞣废水中铬的定性特征曲线。利用吸光度加合定律对大量实测数据进行统计处理。建立测定铬的实验室校准直线方程，相关系数γ＝０．９９６０．以此作为测定铬鞣废水及回收铬渣中铬量的实验室回归直线方程。并对本法的可靠性进行研究，结果令人满意。本法不仅大大简化了铬量测定的步骤．而且在提高分析效率的同时获得同等的检测结果。

| Abstract: | The characteristic curve to determine chromium in tannery wastewater was systematically studied and numbers of data measured were statistically processed using the principle of absorbency additivity,thus establishing a laboratory calibration equation for measuring chromium(y=0.9960).The established equation serves as a regression linear equation to determine chromium concentration in tannery effluents or in chromium sediment.Investigation into the methodological reliability of the method has presented satisfactory results.It is shown that the Crmeasuring method not only can simplify the procedure of measurement but can improve efficiency simultaneously with achieving comparative measurement results. |
