Adsorption Study of Cadmium (II) and Lead (II) On Rice Husk

Year: 2020

Type: article

Abstract: Rice husk was used as an adsorbent for the removal of Cd (II) and Pb (II) from aqueous solution. The effects of contact time, pH, concentration, agitation speed, and dose on the removal of Cd (II) and Pb (II) have been evaluated. Our result shows that rice husk powder has high reduction efficiency for both metals. Results showed that low-cost adsorbents can be fruitfully used for the removal of heavy metals with a concentration range of 30–40 g/l. The percentage removal of heavy metals was dependent on the dose and concentration of Rice husk. The contact time necessary for maximum adsorption was found to be 35-40 min. The optimum pH range for heavy metal adsorption was 4–8.
