Abstract

Adsorption process has been widely used for removing pollutant from water because it is simple, fast, cost-effective and environmentally friendly. This study was conducted to investigate the optimum conditions for humic acid (HA) adsorption from leachate by zeolite, activated carbon and biochar. The results showed the optimum conditions were 60 min contact time, 50 g/L adsorbent dosage and solution pH of 3. The HA removal efficiencies of zeolite, activated carbon and biochar were 52.77%, 99.65% and 79.90% respectively. The effects of humic acid-zeolite (HAZ), humic acid-activated carbon (HAC) and humic acid-biochar (HAB) on plant growth within 10 days (early stage) and 5 weeks (late stage) were also studied. HAZ had shown the best performance in effects on plant growth. Biochar was suggested in this study as it possesses reasonable HA removal efficiency, acceptable effects on plant growth with low purchase price.
