Experimental and kinetic studies on methylene blue adsorption by coir pith carbon
Bioresource Technology, 2007Varying the parameters such as agitation time, dye concentration, adsorbent dose, pH and temperature carried out the potential feasibility of thermally activated coir pith carbon prepared from coconut husk for removal of methylene blue. Greater percentage of dye was removed with decrease in the initial concentration of dye and increase in amount of ...

Comparison of nickel adsorption from electroplating rinse water by coir pith and modified coir pith
Chemical Engineering Journal, 2008The coir pith was used as an adsorbent for nickel removal because the coir pith contains high lignin (36%) and cellulose (44%). The optimum condition for nickel removal by coir pith in a batch system was solution pH 4–7, adsorbent dosage of 5% (w/v), an equilibrium contact time of 10 min and a temperature of 30 °C.

Studies on Gasification of Coir Pith
Journal of Agricultural Engineering (India), 2007Coir pith is considered as an undesirable waste of coir industries. It is difficult to burn coir pith in normal atmospheric conditions. It decomposes slowly, taking 8-10 years for complete decomposition due to higher lignin content of 37 to 45%. Being dust, it is easily blown by wind. When ignited, it does not burn completely and emits continuous smoke

Chromium removal from electroplating wastewater by coir pith
Journal of Hazardous Materials, 2007Coir pith is a by-product from padding used in mattress factories. It contains a high amount of lignin. Therefore, this study investigated the use of coir pith in the removal of hexavalent chromium from electroplating wastewater by varying the parameters, such as the system pH, contact time, adsorbent dosage, and temperature. The maximum removal (99.99%

Properties of Cement Composites Containing Coir Pith
Advanced Materials Research, 2014Application of agricultural waste materials as building materials not just provides solutions of environmental problems related to the waste management, but it also decreases the use of limited available natural resources and energy. The research in this work is focused on using coconut waste, in the form of natural and chemically treated coir pith, as

Study of Physical Properties of Coir Pith
International Journal of Green Energy, 2006Coir pith is a byproduct of the coir industry, producing more than 7.5 million tones annually in India. It can be used as fuel in loose form or in briquettes. This study investigates different physical properties of coir pith with respect to its moisture content (10.1 to 60.2%w.b.) and particle size (0.098 to 0.925mm).

Coconut coir pith lignin: A physicochemical and thermal characterization
International Journal of Biological Macromolecules, 2018The structural and thermal features of coconut coir pith lignin, isolated by three different extraction protocols incorporating two different energy supply sources, were characterized by different analytical tools. The three different chemical extraction protocols were alkaline - 7.5% (w/v) NaOH, organosolv - 85% (v/v) formic and acetic acids at 7:3 (v/

Alkali-treated coir fibre-pith composite for waste water treatment
Journal of Industrial Textiles, 2021Coir fibre and pith are eco-friendly material used in the preparation of composites. Coir fibre and coir pith were treated with sodium hydroxide to study the effect of alkali for prolonged exposure on its properties. Fibre and pith were treated with different concentrations of NaOH from 5% to 30% for 24 hours at room temperature.
