Color removal from wastewater has been a matter of concern, both in the aesthetic sense
and health point of view. Color removal from textile effluents on a continuous industrial scale …

The production of functional activated carbon materials starting from cheap natural
precursors using environmentally friendly processes is a highly attractive subject in material …

In this study, an activated wakame biochar material (AWBM) was prepared by a one-step
calcination and activation method, whose adsorption performances for methylene blue (MB) …

Application of saw dust for the removal of an anionic dye, tartrazine, from aqueous solutions
has been investigated. The experiments were carried out in batch mode. Effect of the …

In this study, natural core-shell structure activated carbon beads (ACBs) from Litsea
glutinosa seeds were successfully produced, characterized, and applied for adsorption of …

Pine cone a natural, low-cost agricultural by-product in Australia has been studied for its
potential application as an adsorbent in its raw and hydrochloric acid modified form. Surface …
