The adsorption of formaldehyde on bentonite and kaolin was studied in batch mode. Parameters like adsorbent dose, pH, contact time and agitation speed were investigated. Langmuir, Freundlich and Temkin isotherms were employed for describing adsorption equilibrium. The maximum amounts of formaldehyde adsorbed (qmax) , as evaluated by Langmuir isotherm, were 3.41 and 5.03 milligrams per gram of ground kaolin and bentonite, respectively. The study results led to the conclusion that kaolin and… CONTINUE READING
