A chemometric study on the effect of feedstock choice and pyrolysis conditions on biochar production and its influence on the remediation of pharmaceuticals from aqueous solutions
(Institute of Chemistry Ceylon, 2021-06) Fernando,Sachin; Peiris,Chathuri; Abeysundara,Sachith. P; Gunatilake,Sameera .R
Removal of antibiotics and non-steroidal antiinflammatory drugs (NSAIDs) from aqueous ecosystem is a serious concern due to their extensive usage and resulting the adverse effects on human and ecological health.
Correlation and the Impact of Feedstock Type and Production Conditions on Heavy Metal Adsorption by Biochar: A Comprehensive Meta-Analysis
(Institute of Chemistry Ceylon, 2021-06) Samarakoon,Vindya; Peiris,Chathuri; Abeysundara,Sachith. P; Gunatilake,Sameera .R
Biochar (BC) is a ubiquitous, porous, carbonaceous solid produced by the pyrolysis of biomass under anaerobic conditions, which can be used as a fuel as well as an adsorbent.
Evaluation and correlation of the influence of production parameters on biochar characteristics and its influence on the adsorption of three industrial dyes
(Institute of Chemistry Ceylon, 2021-06) Saumya,Dineth; Peiris,Chathuri; Abeysundara,Sachith.P; Gunatilake,Sameera. R
Remediation of waste water containing hazardous dyes using biochar (BC), as an adsorption technique, is a cost effective and efficient method. As a statistical approach, this study was focused on how feedstocks, pyrolysis temperature, production method and modification affect to the physiochemical properties of BC and how these properties affect to the adsorption of methylene blue (MB), crystal violet (CV) and rhodamine B (RB) from aqueous medium.
Exploring the role of biochar as a soil amendment
(Institute of Chemistry Ceylon, 2020-09) Peiris,Chathuri
The anaerobic, thermal decomposition of biomass leads to the formation of a stable carbonaceous adsorbent that is termed biochar (BC). In the recent past, BC has gained remarkable research interest as a cost effective alternative to activated carbon.
Influence of feedstock and production conditions on characteristics of biochar and its correlation for the adsorption of oxyanions: A Comprehensive meta-analysis
(Institute of Chemistry Ceylon, 2021-06) Sutherson,Lilogini; Peiris,Chathuri; Abeysundara,Sachith. P; Gunatilake,Sameera .R
Water contamination by oxyanions can be considered as a major environment problem. Biochar (BC) is a carbon rich porous material produced via biomass pyrolysis under limited oxygen condition.
