4.1?CCl4 and CHCl3 may be present in trace amounts in liquid chlorine. The use of chlorine to purify water would then transfer these compounds to the water. Therefore, when the concentrations of the CCl4 and CHCl3 in the liquid chlorine are known, the maximum amounts contributed to the water by the chlorine can be estimated. |
