Sorption of some textile dyes by beech wood sawdust

Journal of Hazardous Materials, 2009
The purpose of this paper is to establish the experimental conditions for removal of several textile dyes from aqueous solutions by sorption on beech wood sawdust, an industrial waste lignocellulosic product. From the six dyes tested, the sorbent shows preference for three dyes: Direct Brown, Direct Brown 2 and Basic Blue 86.

Synthesis and Raman characterization of wood sawdust ash, and wood sawdust ash-derived graphene

Diamond and Related Materials, 2021
Abstract In the present work, we report the synthesis, Raman characterization and comparison of the Raman spectra of the wood sawdust ash (WSA) and graphene produced from this WSA at different temperatures and burning times. For this purpose, the wood sawdust (WS) was burnt at different temperatures (300, 400 and 500 °C) at a constant time of 60 min,

Microwave absorbing material using rubber wood sawdust

2011 IEEE Symposium on Wireless Technology and Applications (ISWTA), 2011
A flat microwave absorber working at frequency 1.8GHz was developed by impregnation of activated carbon and polyurethane. The activated carbon is prepared from the conversion of rubber wood sawdust through chemical activation process using ZnCl 2 solution as the precursor agent. The process involves leaching, heating and washing.
