Water absorption and swelling characteristics of coir pith particle board
Bioresource Technology, 2000Abstract The water absorption and swelling characteristics along the surface and thickness were determined for particle boards made from coir pith of 0.4, 0.8, 1.2 and 2.1 mm average particle sizes using phenol–formaldehyde and urea–formaldehyde resins.

Solid substrate fermentation of coconut coir pith for cellulase production
Enzyme and Microbial Technology, 1994Abstract Coconut pith, available in abundance, especially in tropical countries, can be an excellent new substrate for the production of cellulase enzyme by solid substrate cultivation of Trichoderma viride NCIM 1051. The effect of type of pretreatment, type and level of nutrient medium, inoculum volume, average substrate particle size, and time of

Mechanistic studies on the binding of Acid Yellow 99 on coir pith
Bioresource Technology, 2011The interaction of Acid Yellow 99 (AY 99) with coir pith has been investigated in aqueous medium to understand the mechanism of adsorption and explore the potentiality of this biomass towards controlling pollution resulting from textile dyes. The obtained results establish that one gram of coir pith can adsorb 442.13 mg of AY 99. The adsorption process

Uranium removal from aqueous solution by coir pith: equilibrium and kinetic studies
Bioresource Technology, 2005Basic aspects of uranium adsorption by coir pith have been investigated by batch equilibration. The influence of different experimental parameters such as final solution pH, adsorbent dosage, sorption time, temperature and various concentrations of uranium on uptake were evaluated. Maximum uranium adsorption was observed in the pH range 4.0-6.0.

Pressure Density Relationships and Stress Relaxation Characteristics of Coir Pith
Journal of Agricultural Engineering Research, 1999Abstract The pressure density relationships and stress relaxation characteristics of coir pith were investigated for the particle size and moisture content range of 0·68–2·18 mm and 19·4–64·1% w.b., respectively. The pressure required to densify the coir pith ranged from 1 to 416 kPa for the bulk density range of 61·5–400·2 kg/m3.

The Reaction Kinetics for Coir Pith Pyrolysis in Thermogravimetric Analyzer
Energy Sources, Part A: Recovery, Utilization, and Environmental Effects, 2010Abstract The decomposition behavior of biomass when subjected to thermal stress is different for each kind of biomass. Modeling a pyrolysis or gasification process is complex because the mechanism of decomposition is highly dependent on its mass loss characteristics.

Mechanical and Thermal Properties of Composites Containing Waste Coir Pith
Advanced Materials Research, 2014Agricultural waste materials can often find an application in the production of concrete or mortar. In this paper, several composites containing waste coir pith are studied. A reference material without coir pith is analyzed as well, for the sake of comparison. The investigated material parameters include the basic physical properties determined by the

A Study on Cation Exchange Capacity of Sieved Coir Pith
2018Coirpith which can be regarded as the short fibers and dusts is a lignocellulosic biomass and a recalcitrant one under ordinary conditions. It has the innate character of exchanging ions from the inner matrix which consists of minute pores. In the present study, the ion exchange capacity of coir pith was carried out and was subjected particle size. The
