Abstract

A new modified method was applied to the determination of chloride anion in brackish water by using a common copper(II) sulfate solution and a spectrophotometer. The result of the quantitative analysis demonstrated that chloride concentrations were 1.61% w/v and 1.74% w/v at ebb tide and flood tide, respectively, of the Muya River. On the other hand, chloride concentrations were 1.17% w/v at ebb tide and 1.65% w/v at flood tide of the Yoshino River. The new method proved that chloride concentration corresponded well with results from Mohr and conductive methods. Therefore, the newly developed method can be exploited as common means to measure chloride concentration in aqueous solutions. Moreover, it is also valuable for application to other types of environmental samples.
