| Abstract: | Chrome azurol S(CAS) can combine to color compounds with calcium(Ca) and magnesium(Mg).Surfactants Tween-80 was used as synergists to improve the stability of system.The amount of individual reagent was fixed by using Orthogonal Experimental Design.The contents of Ca and Mg in samples are analyzed by K-Matrix,and calculated by the program of computer.The results were satisfactory. |
