The dependence of molybdate ion sorption in co-precipitated iron and manganese hydroxides (CPH) on the value of pH solutions and the salt background has been described. Industrial wastes of manganese sulfate MnSO4•5H2O (from hydroquinone production) and iron sulfate FeSO4•7H2O (waste production of titanium dioxide pigment) were used for the obtaining of CPH hydroxides.
