Abstract :By doping ZrO2 to the SiO2 with aerogel; the Coinsert ignore into journalissuearticles values(II); and Seinsert ignore into journalissuearticles values(VI); from metal and glass industry wastewaters can be removed due their large surface area and high pore volume. For maximum Seinsert ignore into journalissuearticles values(VI); and Coinsert ignore into journalissuearticles values(II); adsorptions insert ignore into journalissuearticles values(99% and 96%); the optimum Nano-SiO2 / ZrO2-Calcium Alginate Aerogel composite concentrations was found as 4 mg/l, at a pH of 6.0 at a temperature of 80 0C after 45 min contact time. Nano-SiO2 / ZrO2-Calcium Alginate Aerogel were reused with the percentages of 83 % and 87% for Coinsert ignore into journalissuearticles values(II); and Seinsert ignore into journalissuearticles values(VI);, respectively after four sequential utilisation. This reduce the treatment cost by 38%.
