摘要
介绍用分光光度法测定含铬量较高的废水。在酸性条件下,铬与二苯碳酰二肼生成紫红色的配合物,最大吸收波长的540nm。该方法具有简便、快速、应用范围广等特点。
This article aims at dealing with the measurement of the waste water containing high content of chrorimium by means of spectrocolorimetry . under the condition of composition, chrorimium together with diphengl carbazide is generated into purple comound,the biggest absorbed wave length is 540nm, This way is easy to operate and takes short ime, so it can be widely used.
