Abstract Wastewaters containing organic and inorganic contaminants such as dyes, heavy metal ions, salts, and surfactants are considered to be a serious environmental problem in human society. Adsorption is the most popular technique for wastewater treatment. In this paper, a new mesoporous silica-alumina oxide (97% SiO 2 , 3% Al 2 O 3 ) synthesized by pyrogenic method was proposed as a sorbent for acid (C.I. Acid Orange 7), reactive (C.I. Reactive Black 5) and direct (C.I. Direct Blue 71) dyes… CONTINUE READING
