“…With regard to adsorption of CR using magnetic loaded papaya seed powder, Munagapati et al 70 demonstrated that a 0.1 mol L −1 solution of NaOH showed the highest desorption efficiency of 96.3%. In contrast, the use of NaCl, CH 3 COOH, HCl and H 2 O resulted in low desorption efficiencies of 72.6%, 54.2%, 38.3% and 24.8%, respectively.…”

“…Electrostatic interaction and hydrogen bonding also play an efficient role in removing CR by Fe 2 O 3 -PSP. 70 Steroid oestrogensanother class of contaminant in the endocrine disruptor groupwere removed from water using a new visible-light p-n ZnO/graphene oxide (GO) supported on clay and CPS. It was prepared by combining pure kaolinite clay, ZnCl 2 and crushed CPS in a weight ratio of 1:4:1 to obtain K-ZnO/C, while K-ZnO/C/GO was obtained by reacting 1 g graphene oxide.…”

“…66 CPS, an agricultural waste product from pawpaw, has been explored as an adsorbent (activated carbon) 50 or component of composites used either as adsorbents or photocatalysts for the removal of contaminants in water. CPS has been extensively used as an efficient adsorbent for the purification of water polluted by dyes, 50,[67][68][69][70] pharmaceuticals, [71][72][73] heavy metals [74][75][76][77] and anions. 48 Despite the abundance of research studies on the use of CPS in the remediation of environmental contaminants, there is a lack of recent comprehensive reviews on the subject.…”

The advent of civilization, coupled with growing industrialization in many countries, is placing more demand on the available water sources. At the same time, the daily surge in wastes generated by man's anthropogenic activities has led to microbial, organic and inorganic contamination of water sources. Based on available evidence, significant research efforts are being made into the use of low‐cost agricultural materials such as Carica papaya seed (CPS) in the removal of these contaminants from water sources in a bid to provide clean water. In the present review, the organic, inorganic and microbial contaminants in waters were elucidated. Furthermore, the chemical composition of the CPS was illustrated. The adsorption capacity and efficiency of CPS and their composites in the remediation of the selected contaminants were discussed while identifying the various factors affecting the adsorption efficiency. Finally, the reusability of this agricultural material was discussed. Solution pH was identified as a major factor influencing the sorption process. The high removal efficiency reported in the studies that adopted CPS showed its vast potential in the elimination of contaminants from water sources. Also, the regenerative potential of the adsorbent over several cycles indicated its long‐term use. The economic feasibility and environmental sustainability afforded by using CPS chart a path for further investigation into the use of other low‐cost agricultural materials in the elimination of environmental contaminants. © 2023 Society of Chemical Industry (SCI).
