Abstract
In the present scenario, pure drinking water is a great problem. Scientists are finding out ways to combat this problem. Various approaches are being used for water remediation, but there is always a need to get more economical, eco-friendly and viable method for removal of pollutants from water. In the present study, an attempt have been made to prepare composite (RHAC/SnO2) from biochar from rice husk and SnO2. The comparison of adsorption and photo catalysis for removal of methylene blue (MB)has been done. It was concluded that biochar is efficient in removal of MB by adsorption at all the tested pH, whereas SnO2 has removed 75% MB by adsorption at pH 10. The RHAC/SnO2 composite was found to be a better adsorbent of MB with 90% efficiency, whereas its photocatalytic activity was less with 61% efficiency at pH 10. The present findings need to be further explored so as to get a better insight of the prepared composite.
