摘要
本文在同一份试样中控制pH9.0±0.5,加入BCO、PAR两种显色剂,使Cu～BCO,Zn～PAR生成有色配合物,因两种配合物的最大吸收峰值差甚远,490nm、600nm,互不干扰。因而可分别在各自最大吸收波长进行测定,相对误差小于6％,可配合要求迅速出分析结果的大批选矿试样的分析。
In our experiment, Cu-BCO and Zn-PAR yielded the coloured complex compound by controlling pH at 9.0 ±0.5 in the same sample and adding two developevs BCO, PAR. Because there is a great difference between the maximal absorbent peak values of the two complex compounds ( the wave-length is 490nm, 600nm ), they cannot interfere with each other , and so can be detemined respectively. The relative error is less than 6 %. It can be used for analysing a number of ore dressing samples at the same time as quick results are usually expected.
