IC was used for chloride determination for NF rejection experiments. Anions could not be analysed using IC, as humic substances interfere with the analysis (Hoffmann et al. (1986)). A MilHpore Waters Model 590 instrument was used with a Model 430 Conductivity detector. The eluent used was 0.68 gL boric acid (HjBOj), 0.235 gL gluconic acid anhydride (C6HioO< ) and 0.3 gL lithium hydroxide (LiOH 6 H2O).
