“…For wastewaters containing high copper concentration and relative concentration of zinc, nickel and cyanide, the weak complexes of nickel and zinc are present in negligible concentrations. In contrast, copper-cyanide complexes are present in appreciable quantity, due to high affinity of copper by cyanide (Bose et al, 2002).…”

“…Metal cyanides can occur of various forms in the wastewaters, generated from electroplating industries, depending of the solution pH (Patil & Paknikar, 1999;Bose et al, 2002). For wastewaters containing high copper concentration and relative concentration of zinc, nickel and cyanide, the weak complexes of nickel and zinc are present in negligible concentrations.…”

“…Так, в [23] отмечается, что «промышленные сточ-ные воды, содержащие тяжелые металлы и цианиды, требуют очистки для удаления из них металлов и ци-анида перед утилизацией. Обычные методы для об-работки таких сточных вод включают щелочное хло-рирование для разрушения цианида, последующую корректировку уровня pH для осаждения металла и последующее удаление осадка путем разделения твердой и жидкой фаз процесса».…”

“…A principal diferença entre os sedimentos coletados nas Barragens de Timbopeba e Natividade consiste no teor de óxidos de ferro 24 . Considerando que a matriz dos sedimentos é composta basicamente por uma mistura de óxidos de ferro e aluminossilicatos, minerais cada vez mais utilizados como imobilizadores de metais em áreas contaminadas [25][26][27][28][29][30][31] , e o baixo custo do processo, este trabalho objetivou avaliar o uso dos sedimentos das barragens de contenção do processamento do minério de ferro como minimizador da contaminação de metais em águas por processos de adsorção nas fases minerais do sedimento.Para atingir este objetivo e considerando a complexidade dos processos de retenção de metais por sedimentos, este trabalho foi desenvolvido em três partes com a utilização de diferentes méto- …”
