Coprecipitation of tellurium(IV), molybdenum(VI), and lanthanum(III) compounds from hydrochloric acid solutions

We have investigated the coprecipitation of tellurium(IV), molybdenum(VI), and lanthanum(III) hydroxides from hydrochloric acid solutions of compounds of these elements and found conditions under which the precipitate was identical in composition to the starting solution of macrocomponents.
