Adsorption Efficiency of <i>Albizia Lebbeck </i>(Indian Siris) As Bio-adsorbent for Quantitative Removal of Lead Metal Ion from Contaminated Waters

Facile Synthesis of Citric Acid Functionalized Fe3O4@Activated Carbon Magnetic Nanocomposite for Efficient Adsorption of Brilliant Green Dye from Wastewater

“…The Freundlich isotherm model makes several assumptions about the adsorption process, including that it takes place on a non‐homogeneous surface, that the removal rate will rise as the BG dye concentration increases, and that it is a multilayer process [52] . According to Freundlich, binding strength diminishes with increasing site occupancy because the stronger binding sites are covered first by the adsorbate molecules [53]…”

Performance of a Continuous Solar Water Disinfection System in Isiolo County, Kenya

“…Escherichia coli, total coliforms, Staphylococcus aureus and total plate counts indicated the extent of pollution of River Isiolo (Oludairo et al, 2015;Muhammad et al, 2017). The contamination levels exceeded 1 CFU/ml recommended for standard drinking water (Mahananda et al, 2010;Manhokwe et al, 2013)…”
