Sedimentation of pollutant­containing aggregates during purification of wastewater from coking plants

An improved method for high photocatalytic performance of ZnAl2O4 spinel derived from layered double hydroxide precursor

“…Among phenolic compounds, p-nitrophenol (hereafter pNP) is widely applied in various industries, but pNP as a recalcitrant organic contaminant obtains high toxicity in the aquatic environment [1][2][3]. Recently, several techniques such as adsorption [4], advanced oxidation [5], biological treatment [6], coagulation and flocculation [7] have been developed to reduce phenolic compounds from watery solutions. Nevertheless, the materials for the removal of pNP obtain complicated problems, including low surface area and pore volume.…”
