Abstract：The determination of sulfides in water body usually adopted methylene blue spectrophotometry and iodometry. However, these two methods had some problems such as complicated detection procedures and many influencing factors. In the study, the zinc acetate was added to convert the sulfides to zinc sulfide. After suction filtration, the insoluble substances were transferred into 25 mL colorimetric tube. Then, 1.0 mL of 0.1 mol/L sodium hydroxide solution and 5.0 mL of 30% hydrogen peroxide solution were added. After dilution to the mark with water, the solution was heated in water bath at 90 ℃ for 50 min. The zinc sulfide could be quantitatively converted to zinc sulfate. After suction filtration again, the solution medium was adjusted to 5% (V/V) nitric acid. The content of sulfur was determined by inductively coupled plasma atomic emission spectrometry (ICP-AES). Thus the determination method of sulfides in water body by ICP-AES was established. The mass concentration of sulfur in range of 1.00-200.00 mg/L had good linearity to the corresponding emission intensity. The correlation coefficient of calibration curve was r=0.999 8. When the sample volume was 2.0 L, the detection limit of method was 0.002 2 mg/L, and the low limit of determination was 0.007 4 mg/L. The recovery tests were conducted using five actual water samples according to the experimental method. The recoveries were between 97% and 102%. The content of sulfides in three actual water samples was determined by the proposed method, and the found results were consistent with those obtained by national standard method (GB/T 16489-1996). The relative standard deviations (RSD, n=11) were between 0.09% and 5.0%.
