【摘要】：建立了一种利用电极电位快速测定PDS脱硫液中硫离子含量的分析方法。条件为水杨酸钠质量浓度100g/L、抗坏血酸质量浓度16g/L、氢氧化钠调p H至13配制SAOB缓冲剂,将脱硫液待测液与SAOB缓冲剂按体积比1∶9混合后进行测定。电极响应时间0~2min,稳定性好,脱硫液中的大量副盐离子对分析结果基本无影响,测定结果与碘量法测定结果相对偏差在7%以内,与碘量法无显著性差异。该法具有成本低、简便快速,利于推广等优点。
[Abstract]:A method for the rapid determination of sulfur ion content in PDS desulphurization solution by electrode potential was established. The conditions were as follows: the mass concentration of sodium salicylate was 100 g / L, the concentration of ascorbic acid was 16 g / L, and the buffer of SAOB was prepared by adjusting pH to 13 of sodium hydroxide. The desulphurization solution to be measured was mixed with SAOB buffer at 1:9. The electrode response time is 0 鈮，
