Experimental and kinetic studies on methylene blue adsorption by coir pith carbon.
D. Kavitha,Chinnaiya Namasivayam +1 more
TL;DR: Kinetic study showed that the adsorption of dye on coir pith carbon was a gradual process and pH effect and desorption studies suggest that chemisorption might be the major mode of the Adsorption process.

The role of sawdust in the removal of unwanted materials from water.
TL;DR: Sawdust, a relatively abundant and inexpensive material is currently being investigated as an adsorbent to remove contaminants from water as discussed by the authors, and chemical substances including dyes, oil, toxic salts and heavy metals can be removed very effectively with the organic material.
