Sorption recovery of arsenic and antimony from nickel-containing solutions using manganese (IV) oxide

The optimal conditions for the sorption of arsenic and antimony from nickel-containing solutions on freshly obtained manganese dioxide have been found (pH 2, coagulation time of the precipitate 75 min, addition of 2.0 mmol MnSO4 and 0.2 mmol KMnO4 per 50 ml). It was found that the Freundlich model d...

Description
Summary:The optimal conditions for the sorption of arsenic and antimony from nickel-containing solutions on freshly obtained manganese dioxide have been found (pH 2, coagulation time of the precipitate 75 min, addition of 2.0 mmol MnSO4 and 0.2 mmol KMnO4 per 50 ml). It was found that the Freundlich model describes the process of adsorption of arsenic and antimony on manganese dioxide most accurately (the correlation coefficient for antimony and arsenic was 0.98 and 0.99, respectively). According to the developed procedure, reference materials of nickel alloys were prepared for further determination of arsenic and antimony using inductively coupled plasma atomic emission spectrometry. The certified and found values of the antimony and arsenic content in the samples were in good agreement.
