Abstract

The concept on ┐fractional” precipitation of hydroxides has been refined. In the preparation of coprecipitated Al(III)−Mg(II) hydroxides at variable pH values, mixed aluminium-mangesium compounds are formed not only in alkaline but also in acidic media.

Abstract

Уточнены представления о “дробном” осждении гидроксидов. Установлено, что при полугении сооажденных гидроксидов Al(III)−Mg(II) при переменном значении pH формирование смешанных алюмомагниевых соединеий происходит не только в щелочной, но и кислой среде.
