“…In contrast to the early studies discussed above which used lignin from the cooking stage [117,121], the complete removal of COD from bleached effluents was not possible, and complete color removal was only achieved for coagulated wastewater samples [128]. Furthermore, free TiO 2 and ZnO or silica gel/porcelain-supported ZnO achieved considerable color clearance as well as the removal of phenols [123]. The efficiency of color clearance differed between the free and supported catalysts, mainly reflecting the better physical adsorption of organic compounds to suspended particles compared to those supported on a substrate [123].…”

“…Os resíduos foram submetidos a diversos processos avançados de degradação (fotocatálise heterogênea e peroxidação assistida por radiação ultravioleta), aplicados de acordo com procedimentos descritos previamente 7,8 . Para o efluente papeleiro de branqueamento 30 amostras foram produzidas, 11 das quais foram reservadas para calibração e 19 para validação.…”
