Methylene blue removal using coconut shell biochar synthesized through microwave-assisted pyrolysis

Indonesia is the world’s second largest producer of coconut. This at the same time resulted in huge generation of coconut shell waste that need to be properly managed to prevent environmental contamination such as water, air and soil pollution. Current techniques of physical and thermal processing a...
