Abstract

To detect chlorine residual in water in methyl red spectrophotometry. Under acid medium, chlorine residual may make methyl red discoloration. The largest absorbing wave length was (524 nm,) mol-absorbing coefficient was 1.25×10~4 L/mol·cm. When mass concentration of chlorine residual was between 0.0 mg/L～1 mg/L, it relied on Bill Law. The plus quantity of methyl composite solution, the absorbing value's stability of discoloration sample solution, were tested. And the test result was compared with DPD spectrophotometry. Their detection results were same.
