Methylene blue, a prevalent cationic type dye, has been extensively utilized in textile
industry. Lignin generates as a byproduct and its utilization is required to add a potential …

Adsorbents that effectively remove dye substances from industrial effluents are needed for
the protection of human health and the natural environment. However, adsorbent …

This study investigated the adsorption performance of methylene blue using Ca (OH) 2-
modified biochar derived from agricultural and forestry wastes. The results showed that the …

Oak wood, an agrowaste, was activated to prepare biochar and used as an effective
biosorbent to remove methylene blue (MB) dye from aqueous solution. The properties of the …

Biochar from peanut shell was used as the precursor for the preparation of porous biochar
by KOH activation. The pore structures of porous biochar also were characterized by …

Improperly treated or directly discharged into the environment, wastewater containing dyes
can destroy the quality of water bodies and pollute the ecological environment. The removal …

Novel adsorbents were produced through the grinding of biochars of different feedstock and
pyrolysis temperature in a planetary ball mill. The removal effectiveness and mechanisms of …

Biochar is a low cost and renewable adsorbent which can be used to remove dye from
wastewater. Cattle manure-derived low temperature biochar (CMB) was studied to remove …

Biochar derived from eucalyptus saw dust modified with citric, tartaric, and acetic acids at
low temperatures was utilized as adsorbent to remove methylene blue (MB) from aqueous …

The biochar adsorption process is very efficient in the treatment of wastewater treatment. In
this study, Moringa oleifera seeds-derived biochar (B) was modified using chitosan-ZnO …
