Biochar: a sustainable solution (2020, methodology): “Remediation techniques which have been developed for the removal of heavy metals from contaminated water include (Gunatilake 2015): (1) Physico-chemical methods- physical separation (mechanical screening, flotation, electrostatic separation, magnetic separation and attrition scrubbing), chemical pro”
Environmental application of biochar: Current status and perspectives. (2017, background): “Moreover, wastewater from oil and mines, pharmaceuticals and chemical industries were treated using hardwood- and softwood-derived biochars (Frankel et al., 2016; Gunatilake, 2015).”
Carbon-based nanomaterials for remediation of organic and inorganic pollutants from wastewater. A review (2020, background): “Nevertheless, some of those methods have limitations such as high operational cost, production of a high amount of sludge which results in the generation of secondary pollutants, and economically not viable (Gunatilake 2015; Oguz 2017; Boikanyo et al. 2018; Crini and Lichtfouse 2020).”
