Removal of Basic Red 46 Using Low-cost Adsorbent of Hardened Paste of Portland Cement From Contaminated Water

The present study was carried out to investigate the potential of hardened paste of Portland cement (HPPC) as a low-costadsorbent for the removal of Basic Red 46 from contaminated water by using batch adsorption studies. In present study HPPChas been selected as adsorbent because of the main advantages such as no sludge production, abundant availability and lowcostmaterial. The effect of contact time, adsorbent dosage, pH, temperature and adsorbent particle size were examined in theadsorption process with HPPC. Results showed that removal of BR46 increased over 80 percent with increasing adsorbentdosage, temperature, contact time, pH and adsorbent particle size decreasing. Therefore, it may be concluded that HPPC wasan efficient and economical adsorbent. J. Color Sci. Tech. 2(2009), 221-226.© Institute for Colorants, Paint and Coatings.
