“…The granulated zeolite reaches to contain up to 66 % of the Arsenic that is present in water (Rubio-Arias et al, 2021). This water quality management process in Ecuador is controlled by the National Water Secretariat (SENAGUA), for the analysis of organic matter and metal content that may cause an unpleasant taste or odor in water for human intake (Ramírez-Palma et al, 2019).…”

Water is an essential resource for life, however, due to the constant worldwide population growth, this consumption also increases every time (García-Loor et al., 2020). Previously, civilizations used water from natural sources, such as rivers or lakes, but the pollution generated by globalization has caused the presence of physical, chemical, and microbiological agents in these sources. Water is used in agriculture, industry, and consumption by 70, 19, and 11 %, respectively (Bernabé-Crespo et al., 2021). An alternative to this problem was to provide drinking water, organizing storage and distribution systems for this resource. Guarantee the quality of water for human intake has become a challenge, because it is exposed to harmful substances and microorganisms that affect the health of people if they consume it directly (Simbaña et al., 2022). There are several scenarios related to this problem, such as the discontinuity of the service, and the conditions of the domestic distribution lines, among others.

“…[10][11][12] Therefore, the World Health Organization has set the maximum concentration of Pb 2+ , Ni 2+ , and Hg 2+ in drinking water at 0.01, 0.02, and 0.001 mg/L, respectively. 13,14 Currently, scientists are working on the synthesis sorbents to remove heavy metal ions, such as activated carbon, 15,16 zeolite, [17][18][19] diatomite, [20][21][22] and resin. [23][24][25] The treatment of wastewater containing heavy metals using resin has the characteristics of high efficiency and economy, and has good development prospects.…”

In this study, the thiol-functionalized resin (PMA-SH) was prepared directly by a one-step reaction of polymethyl acrylate resin (PMA) and 1,2-ethanedithiol, and it was applied to the adsorption of Pb 2+ , Ni 2+ , and Hg 2+ in aqueous solution. The effects of initial concentration, temperature, contact time, and electrolyte on the adsorption of Pb 2+ , Ni 2+ , and Hg 2+ were investigated. At 308 K, the saturated adsorption capacity of PMA-SH on Pb 2+ , Ni 2+ , and Hg 2+ is found to be 0.94, 0.88, and 0.41 mmol/g, respectively. In addition, the experimental adsorption data were consistent with the Redlich-Peterson model and pseudo-second-order kinetic model. Overall, PMA-SH exhibited good reuse performance as well as excellent adsorption performance for Pb 2+ , Ni 2+ , and Hg 2+ .
