A comparative study of surface modification in carbonized rice husk by acid treatment

Water pollution by heavy metals is a major environmental problem because of their toxicity and its removal is highly essential. In this present investigation, two types of adsorbents were prepared viz. activated carbon from acid treated rice husk (ACARH) and activated carbon from rice husk followed...
