Abstract:
... Agri-wastes biochars viz. eucalyptus bark (EBBC), corn cob (CCBC), bamboo chips (BCBC), rice husk (RHBC) and rice straw (RSBC) and acid treated RSBC (T-RSBC), were characterized for their physico-chemical properties and sorption behaviour of atrazine and imidacloprid was studied. Kinetics study suggested that except atrazine adsorption on RSBC, which was best explained by the pseudo second order m ...

Abstract:
... The decrease of wood supply leads to find out the alternative raw material for particleboard production derived from non-woody cellulose materials, one of the promising material is sorghum bagasse. However, the strength properties of particleboard manufactured from this biomass tend to be low. This research was to evaluate physical, mechanical and durability properties of sorghum bagasse-particleb ...

Eucalyptus; adsorbents; adsorption; atrazine; bamboos; bark; biosorbents; corn cobs; electrostatic interactions; fractal dimensions; imidacloprid; rice hulls; rice straw; sorption isotherms; surface area
Abstract:
... Low cost agro-waste biosorbents namely eucalyptus bark (EB), corn cob (CC), bamboo chips (BC), rice straw (RS) and rice husk (RH) were characterized and used to study atrazine and imidacloprid sorption. Adsorption studies suggested that biosorbents greatly varied in their pesticide sorption behaviour. The EB was the best biosorbent to sorb both atrazine and imidacloprid with K F values of 169.9 an ...
