摘要
脱硫废液中硫的存在形式有单质硫(S)、硫离子(S2-)、硫氰酸根离子(SCN-)、硫代硫酸根离子(S2O32-)、亚硫酸根离子(SO32-)和硫酸根离子(SO42-)。采用化学分析和仪器分析相结合的方法,计算其质量浓度分别为42.5mg/L、838.6mg/L、132.8mg/L、4494.8mg/L、120.0mg/L和466.6mg/L。通过对比硫酸根离子总量的方法对所测结果进行校准,得到总硫量(以硫酸根计)的相对误差为4.7%。
The existing modes of sulfur in desulfurized waste liquor are S, S^2-, SCN^-, S2O3^2-, SO3^2- and SO4^2-. The calculated their quality concentrations are 42.5mg/L, 838.6mg/L, 132.8mg/L,4 494.8mg/L, 120.0mg/L and 466.6mg/L respectively with the combined method of chemical analysis and apparatus analysis. The determined results are calibrated through the method of comparing the total amount of sulfate ion. The relative error of gained total sulfur amount （calculated on basis of sulfate radical） is 4.7%.
