Abstract:

This paper described the principle and operating procedure for determination of NH4SCN content in desulfurization liquid by Fe-thiocyanic acid root complexing colorimetry and the test for interfering ion of SO42-,S2O32- and S2-.This method is proved to be simple in operation,sensitive in reaction and high in accuracy,which could rapidly determine the NH4SCN content in desulfurization liquid.
