针对废水中硫化物的特点，本文按照《水质硫化物的测定碘量法》（ HJ/T60-2000）开展测定硫化物的实验，探讨了硫酸和盐酸对实验结果的影响，明确了空白试验、加药次序、标准溶液配制和滴定终点等容易忽视的步骤。试验表明：应加入盐酸对样品进行酸化，空白实验中必须使用滤纸，在反应过程中要严格控制加药次序，注意观察滴定终点。

Aiming at the characteristics of sulfides in wastewater , according to water quality determination of sulfides -iodometric method (HJ/T60-2000), the influence of sulfuric acid and hydrochloric acid on results was discussed , steps were cleared that easy to overlook such as the blank assay , dosing sequence , preparation of standard solution and titration end point.The test showed that the acidification of samples was necessary with hydrochloric acid , the filter paper must be used in blank test , the dosing sequence in the reaction process should be controlled strictly , and titration end point was observed carefully.
