Adsorption Mechanism of Cr(VI) onto Coir Pith

Bioremediation Journal, 2009
ABSTRACT Reductive adsorption of Cr(VI) on coir pith (hereafter CP) was examined as a function of pH, ionic strength, and temperature. The CP contains 1.33 meq g− 1 phenolic, 0.43 meq g− 1 of lactonic, and 0.35 meq g− 1 carboxylic sites. Thus the CP surface is enriched with electron-donating oxygen functionalities.

Use of coir pith particles in composites with Portland cement

Journal of Environmental Management, 2013
Brazil is the fourth largest world's producer of coconut (Cocos nucifera L.). Coconut crops generate several wastes, including, coir pith. Coir pith and short fibers are the byproducts of extracting the long fibers and account for approximately 70% of the mature coconut husk. The main use of coir pith is as an agricultural substrate.

Batch biomethanation of banana trash and coir pith

Bioresource Technology, 1995
Abstract Anaerobic digestion of banana trash and coir pith was carried out for a period of one month by batch digestion. During biomethanation, reduction of total- and volatile-solids was, respectively, 25.3 and 39.6% in banana trash and 13.6 and 21.6% in coir pith.

Mechanical properties of coir pith particle board

Bioresource Technology, 1999
Abstract Particle boards of size 250 mm × 250 mm and 12 mm thick, with 0·9 g/cc density, were made from coir pith using phenol-fomaldehyde and urea-formaldehyde resins. The mechanical properties, modulus of rupture, tensile strength both parallel to surface and perpendicular to surface, screw-holding capacity along face and along edge, nail-holding ...

Coir Pith: A Potential Agro Residue for Anaerobic Digestion

Energy Sources, Part A: Recovery, Utilization, and Environmental Effects, 2007
Abstract Coir pith is a lignocellulosic agro residue, which is produced in enormous quantities as a byproduct in coir industry of India. Though utility of coir pith has been claimed in different applications, an efficient and accepted technology for its maximum utilization is not yet made available.

A Novel Method for Accelerated Composting of Coir Pith

Energy & Fuels, 2007
Hillocks of coir pith accumulate in the vicinity of coconut coir-fiber extraction units, of which disposal and management remain a major problem. Southern states of India, especially Kerala, Tamil Nadu, Andhra Pradesh, Karnataka, and Orissa, face this problem.

Adsorptive removal of 2-chlorophenol by low-cost coir pith carbon

Journal of Hazardous Materials, 2003
Adsorption of 2-chlorophenol (2-CP) by coir pith carbon was carried out by varying the parameters such as agitation time, 2-CP concentration, adsorbent dose, pH and temperature. Adsorption equilibrium reached at 40, 60, 80 and 100 min for 2-CP concentration of 10, 20, 30 and 40 mg/l, respectively. Adsorption followed second-order kinetics.

Recycling of agricultural solid waste, coir pith: Removal of anions, heavy metals, organics and dyes from water by adsorption onto ZnCl2 activated coir pith carbon

Journal of Hazardous Materials, 2006
The abundant lignocellulosic agricultural waste, coir pith is used to develop ZnCl(2) activated carbon and applied to the removal of toxic anions, heavy metals, organic compounds and dyes from water. Sorption of inorganic anions such as nitrate, thiocyanate, selenite, chromium(VI), vanadium(V), sulfate, molybdate, phosphate and heavy metals such as ...

Use of Coir Pith as a Soil Amendment Material

Asian Journal of Water, Environment and Pollution, 2018
In the present study, an attempt has been made to utilize Coir Pith as a soil amendment material. In this context, laterite soil is taken as the base material and coir pith is added to it externally, with variable ratio to carry out soil fortifications. The major demerit in laterite soil is the presence of nitrogen, phosphorus and potassium, which are

Phosphate Removal from Aqueous Solution Using Coir-Pith Activated Carbon

Separation Science and Technology, 2010
The present study deals with the removal of phosphates from aqueous solution using activated carbon developed from coir pith. Batch adsorption experiments were performed to delineate the effect of initial pH, contact time, adsorbent dose and temperature on the removal of phosphates by coir-pith activated carbon (CAC) (activated by H2SO4).
