Abstract
Inventia se refera la o metoda colorimetrica de determinare a ionului sulfat prin reactia cu o sare de bariu si consta în aceea ca, în scopul obtinerii unei sensibilitati ridicate, utilizarii unor esantioane mici de probe si înlaturarii interferentelor altor ioni se utilizeaza drept sare de bariu cromatul de bariu solubilizat în acid clorhidric diluat cînd se formeaza sulfat de bariu insolubil si se elibereaza o cantitate echivalenta de ioni cromat, care se dozeaza colorimetric cu difenilcarbazida.
