Removal of toxic metals from wastewater by Brazilian natural scolecite

Autor: R. S. Jimenez, Wagner Carvalho, Sandra Maria Dal Bosco

Publikováno v: Journal of colloid and interface science. 281(2)

The cation-exchange capacity of Brazilian natural zeolite, identified as scolecite, was studied with the aim of evaluating its applications in wastewater control. We investigated the process of sorption of chromium(III), nickel(II), cadmium(II), and
