“…In the literature, various parts of cassava are reported to be adsorbents used in the removal of heavy metals, for example, zinc ( [10][11][12][13]), copper ([11, 13-21]), lead ( [20][21][22][23][24][25][26][27][28]), cobalt ( [29,30]), vanadium [30], chromium ([13, 17, 30, 31]), and cadmium ( [12,15,[32][33][34]), dyes such as rhodamine B [35], direct red [36], methylene blue ( [36][37][38][39][40]), methyl orange [40], and reactive dyes [41], antibiotics ([22, 42-44]), phosphorous [45], biodiesel purifcation [46], organic pollutants from industrial efuents ( [29,47,48]), and free fatty acid [49]. In addition, ZnO nanoparticles synthesized from cassava starch are used as adsorbents [50].…”
