| Abstract: | This article deals with the procedure for determining the exchange capaciiy of the China-made chelating resin CR-1.The exchange capacity of CR-1 resin in H+ and Na+ forms was measured,and a correlation experiment was made in comparison with the internationally used Chelex-100 resin. The result shows that the exchange capacity of CR-1 is equal to that of Chelex-100. The absorptive characterization of CR-1 to the heavy metals in spa water was tested.The result proves that CR-1 and Chelex-100 have the similar function. Therefore CR-1 can be used to separate the different species of heavy metals. Nine chemical species of heavy metals in seawater were measured by using CR-1 for the first time. The experiment indicates that this method proves accurate and workable. |
