Abstract

Изобретение относится к способу осаждения арсената кальция с пятивалентным мышьяком из кислого раствора, в котором мышьяк, по меньшей мере частично, находится в трехвалентной форме. Кислый раствор нейтрализуют перед подачей на стадию окисления мышьяка и малорастворимое соединение кальция с мышьяком осаждают из раствора, в котором весь мышьяк является пятивалентным.
