| Abstract: | In ammonia solution zinc(Zn~(2+))can react with zincon to form a blue compound. In this paper with the adsorption behaviour of a colloid solution, the bi-maximum adsorption-wavelengthes spectrophotometry was studied connecting the fading colour and the developing one to analyse Zn. Experiments showed that both precision and sensitivity were high.It was suited to determine zinc of natural water. |
