Abstract

This study optimizes the synthesis process of pellet-type adsorbents using alum sludge. The effect of the binder and heat treatment temperature on the nanopore formation in the adsorbent is investigated. The pellet-type adsorbent prepared using the powder-type sludge from water treatment is determined to be a material that contains nanopores. The specific surface area is increased significantly after the calcination process in the range of 132-172 m2 / g. With the calcination treatment, the breakthrough time in the formaldehyde adsorption increases remarkably with an optimum calcination temperature of 400 - C. The breakthrough capacity of the formaldehyde increases to a maximum 2.96 mg/g at this temperature.
