ABSTRACT The present work was done in order to develop and find out suitable conversion methods for coconut husk wastes into value-added products. It is well-known that coconuts husk waste is hydrophobic therefore ethanol with different doses was used as a surfactant to enhance the removal efficiency. Trea...

ABSTRACT Snail shell waste ( Helix pomatia ) has been evaluated as raw material for the preparation of activated carbon using ZnCl 2 and CaCl 2 with the temperature ranging from 500°C to 800°C. The activated carbon prepared was characterized, showing effect of temperature on ash content, pore volume and porosity. The adsorption isotherm for methylene blue was carried out on the activated carbon in a batch study. The adsorbent exhibited excellent adsorption for methylene blue. The experimental data were used for both Langmuir and Freundlich models. The adsorption coefficients of Langmuir isotherm were found to be 0.996 and 0.957 for CaCl 2 and ZnCl 2 while 0.969 an...
