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 ...

IOP Conference Series: Materials Science and Engineering, 2018 As the city well known for its culture of coffee drinkers, modern and traditional coffee shops are found everywhere in Banda Aceh, Indonesia. High number of coffee shops in the city generates large quantities of spent coffee grounds as waste without any effort to convert them as other valuable products.

Heavy metal removal from industrial effluent using bio-sorbent blends [PDF]
SN Applied Sciences, 2019 There is extensive literature on the use of adsorbents derived from waste to treat industrial effluents containing heavy metal ions. However, there is limited information on the use of adsorbent blends. This is applicable for treating effluents which contain a number of heavy metals, so any one single adsorbent may not be suitable for achieving high ...

Kinetic modelling of dumpsite leachate treatment using Musa sapientum peels as bio-sorbent [PDF]
Global Journal of Engineering and Technology Advances, 2021 Kinetics models are very vital to dumpsite operators and planners as they provide relevant information for effective treatment of leachates. The aim of this work is to model the kinetic process of treatment of Lagos dumpsite leachate using Musa sapientum peels as bio-sorbent with a view of establishing the kinetic parameters of the treatment process ...

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.
