Paper sludge incineration ash (PSIA) is mainly composed of aluminosilicate glass with metal impurities, such as Fe, Ca, Mg, K, P, Ti and Zn. Since the glass is a readily available source of Si and Al for zeolite synthesis, PSIA can be used as a raw material for zeolite. In this study, we investigated the optimum conditions of synthesizing zeolite from PSIA. The synthesized products were characterized using XRD, XRF, EDS, SEM, and FT-IR spectroscopy, mainly composed of Na-P1 zeolite, could be obtained from PSIA with 1 - 2 M NaOH solutions at a reflux temperature. Hydroxy sodalite was formed at higher NaOH concentration (i.e. 3.5-5.0 M). The synthesized zeolite exhibited a high cation exchange capacity (CEC) of 244 meq/100 g.

Keywords:paper sludge incineration ash (PSIA);zeolite;Na-P1 zeolite;hydroxy sodalite;cation exchange capacity (CEC)
