Abstract
A microprocessor-controlled ion selective electrode (MC) method was evaluated and compared to the forward amperometric titration (AT) method for determining total chlorine in condenser cooling river water from coal-burning electric plants. The effective range for quantification by the MC method is from the minimum detection limit of 6.5 micrograms/l chlorine for unspiked condenser water and 13.3 micrograms/l chlorine for spiked condenser water to 100 micrograms/l chlorine. Interferences by zinc(II), copper(II), iron(III), arsenic(III), and manganese(VII) are discussed. The pH, chromium(VI), mercury(II), bromide, and arsenic(V) do not interfere with measurement of total chlorine. For both unspiked and spiked condenser water, the overall pooled standard deviation and overall mean percentage relative standard deviation over concentrations of 20-200 micrograms/l chlorine are lower for the MC method than for the AT method. Standard deviations are discussed for the MC method over concentrations of 2-20 micrograms/l chlorine.
