摘要
在测试液中加入K_2CrO_4和乙醇,提高Ba^(2+)对滴定终点指示的灵敏度,用示波双电位滴定法直接测定了多种天然水样中的,方法简便,结果可靠。
A method for determination of in natural waters with oscillographicpotentiometric titration has been studied. The end point of the titration of with Ba2+ isvery sharp by means of adding K2CrO4 and C2H5OH into the test solution. The method issimple and the results are satisfaetory.
