Utilisation of Exhausted Coffee Husk as Low-Cost Bio-Sorbent for Adsorption of Pb2. [PDF]
Trop Life Sci Res, 2022 This study utilised a bio-sorbent from exhausted coffee husk (ECHBS) for the removal of ion Pb2+ from an aqueous solution. Four different activation methods were conducted by chemical activation with KOH, H3PO4, ZnCl2, and without chemical activation. In addition, the influence of process parameters such as heating temperature, heating time and heating

Wheat Straw as a Bio-Sorbent for Arsenate, Chromate, Fluoride, and Nickel [PDF]
Water, 2017 Batch-type experiments were used to study As(V), Cr(VI), F−, and Ni2+ sorption/desorption on wheat straw. For the lowest concentration added (0.5 mmol·L−1), the sorption sequence was F− > Ni2+ > Cr(VI) >> As(V) (93%, 61%, 29%, 0.3%), but changed to Ni2+ > F− > Cr(VI) >> As(V) when 3.0 and 6.0 mmol·L−1 were added (with 65%, 54 ...

Bio-sorbents: A Novel Technology to Mitigate Heavy Metal Pollution
International Journal of Plant & Soil Science, 2023 The health of living beings is seriously threatened by the toxicity and bioaccumulation tendency of heavy metals in the environment. Heavy metals cannot be broken down by chemical or biological processes, unlike organic pollutants. They can therefore only be changed into less dangerous species.
