| Abstract: | This method is to measure trace chlorine in soil by mercury thiocyanate colorimetry using half-melted mixture of sodium carbonate and zinc oxide. It tested and determined the best addition of each reagent with RSD of 2%-9%. Checked by national standard reference material, the measurement fits certified value in general. |
