“…This example is based on an experimental and modeling study reported by Podder and Majumder. 3 Arsenic(III) and arsenic(V) were removed from synthetic solutions by living bacterial cells immobilized on a solid support. The arsenic uptake process was attributed to biosorption and bioaccumulation.…”

“…Note that the Liu equation is called the Langmuir−Freundlich equation in the work of Podder and Majumder. 3 Another 11 isotherm equations were also fitted to the arsenic(V) data (not shown in Figure 1). Therefore, the original authors 3 tested a total of 30 isotherms against a single data set.…”

Experimental equilibrium data for the adsorption of water contaminants on solid surfaces are generally correlated using suitable isotherm expressions. In most cases, adsorption isotherms are used empirically with the primary aim of finding the best fitting ones. The literature of adsorptive water decontamination is replete with such isotherm comparisons, usually evaluated on the basis of some statistical metrics such as R 2 and RMSE. For example, several studies have compared and ranked the isotherm equations of Hill, Sips, Koble−Corrigan, and Liu. These comparative evaluations imply that the four isotherms possess different data fitting abilities, and consequently it is possible to identify the most accurate one. The present study argues that this commonly held notion is incorrect. It demonstrates that the four isotherms provide the same results when fitted to three previously published data sets. This finding suggests that the four isotherms are mathematically equivalent despite apparent differences in their formulations. Indeed, a mathematical analysis unequivocally shows that the Hill, Sips, Koble−Corrigan, and Liu isotherms can be represented by a single generic equation with three arbitrary fitting parameters. As such, the four isotherms must provide exactly the same fit to a given set of isotherm data.

“…Usually, As removal efficiency increases with the increase in the adsorbent's dosage, due to the higher surface area or exchangeable sites provided. However, if the adsorbent's dosage is too high, the removal efficiency of As will finally stay constant, which is not economic [91][92][93][94]. Take iron-modified peat for example, it was determined that only 60% of the As(V) was removed with an initial concentration of 800 mg • L −1 , and the ratio reached more than 90% when its initial concentration decreased to 300 mg • L −1 [95,96].…”

More than 170 million individuals have been influenced by arsenic (As) because of the ingestion of As-polluted groundwater. The presence of As in water bodies, particularly groundwater, has been found to become a widespread issue in the past few decades. Because arsenic causes extreme wellbeing impacts, even at a low concentration in drinking water, the innovations of As removal from contaminated water are of significant importance. Traditional strategies, for example, reverse osmosis, ion exchange, and electro-dialysis are generally utilized for the remediation of As-polluted water; however, the high cost and/or sludge production restricts their application in less-developed areas. The utilization of adsorbents acquired from natural materials has been explored as an alternative for the costly techniques for As removal. This paper aims to review the past and current developments in using naturals adsorbents or modified natural materials for arsenic removal and show the different parameters, which may influence the As removal effectiveness of the natural adsorbent, such as contact time, adsorbent dosage, flow rate, pH, reusability, temperature, and influence of others ions.
