以往经常用硫酸钡重量法及容量法(包括电位滴定)测定硫酸根,但重量法操作复杂。容量法精度不良。本文应用自制的JZ-1型激光散射测浊仪对水中的硫酸根进行监测,测量范围为0.5～30mg/l SO_4~(2-),灵敏度较高。方法简易、快速、适宜于现场监控。
In the past, barium sulfate weight and volumetric methods (including potentiometric titration) were often used to measure sulfate, but gravimetric method was complicated. Poor volume accuracy. In this paper, the self-made JZ-1 Laser Scattering Turbidimeter was used to monitor the sulfate in water. The measurement range was 0.5 ~ 30mg / l SO_4 ~ (2-), and the sensitivity was high. The method is simple, fast and suitable for on-site monitoring.
