Investigating the catalytic properties of calcium compounds derived from marine based shell waste for wastewater treatment

Marine based shell wastes are considered as under-exploited natural resources in Malaysia. Thus, the present study was concerned with the utilisation of cockle shells to be transformed into calcium oxide (CaO) for the treatment of methylene blue (MB). The synthesised CaO was produced from the calcin...
