Abstract

Inventia se refera la chimie, si anume la un procedeu de captare a ionilor de sulfura si hidrogenosulfura din diverse lichide, inclusiv din diferite categorii de ape, si poate fi utilizata la purificarea apelor potabile, tehnologice si reziduale.Esenta inventiei consta în aceea ca procedeul de captare a ionilor de sulfura si hidrogenosulfura din solutii prevede contactarea solutiei, care contine ioni de sulfura si hidrogenosulfura, cu un schimbator de anioni puternic bazic, prealabil modificat cu Bi(III) prin tratarea a 5 g de polimer cu 250 mL solutie de 0,016 M Bi(NO3)3 cu pH-ul 0,25, la temperatura de 55°C timp de 5,5 ore.Rezultatul tehnic consta în aceea ca procedeul propus nu polueaza apa purificata cu compusi ai sulfului oxidat - ioni de sulfat, sulfit si tiosulfat, precum si cu sulf coloidal, eliminarea caruia din apa este dificila.
