“…Result of Kinetics of this study is agreement with previous study 2 , 39 , 40 . The pseudo-first-order kinetic assumes that the adsorption process is affected by the physiosorption, and the rate-limiting step in adsorption depends on collision between solute molecules of ions with unoccupied single sites at the surface of the adsorbent material The intraparticle diffusion kinetic assumes that the intraparticle diffusion of dye molecules on the adsorbent is the rate-limiting step in the adsorption process 41 . The pseudo-second-order kinetic assumes that the rate-limiting step of adsorption is chemisorption, which is probably ascribed to ion-exchange or sharing of electrons between adsorbents and adsorbate.…”

The need for fresh water is more than before by population growth, and industrial development have affected the quality of water supplies, one of the important reason for water contamination is synthetic dyes and their extensive use in industries. Adsorption has been considered as a common methods for dye removal from waters. In this study, Acid Red18 removal in batch mode by using Granular Ferric Hydroxide (GFH) was investigated. The GFH characterized by XRD, FESEM and FTIR analysis. Experiments were designed using RSM-CCD method. The maximum removal efficiency was obtained 78.59% at pH = 5, GFH dosage = 2 g/l, AR18 concentration = 77.5 mg/l and 85 min of contact time. Optimization with RSM and Genetic Algorithm carried out and is similar together. The non-linear adsorption Isotherm and kinetic fitted with Freundlich (R2 = 0.978) and pseudo-second-order (R2 = 0.989) models, respectively. Thermodynamic studies showed that the AR18 adsorption is endothermic process and GFH nature was found spontaneous.

In the present research paper, a biosorptive remediation practice for an aqueous medium sample polluted with manganese ions was implemented using the activated coastal waste of the Zostera marina plant. This is the first report in the literature on the utilization of current modified biological waste as a biosorbent substance for the removal of manganese ions from the water environment. The analyses of biosorbent characterization, environmental condition, kinetic, equilibrium, and comparison were performed to introduce the ability of prepared biosorbent for the removal of manganese from the aquatic medium. The biosorbent matter has a rough surface with numerous cavities and cracks and various functional groups for the biosorption of manganese. The environmental conditions significantly affected the manganese purification process, and the optimum working conditions were determined to be biosorbent quantity of 10 mg, pH of 6, manganese concentration of 30 mg L-1, and time of 60 min. The pseudo-second-order model best explained the kinetic data of biosorption operation. The biosorption equilibrium data were best described by the Freundlich isotherm. According to the Langmuir equilibrium model, the maximum purification potency was estimated to be 120.6 mg g-1. The comparison work revealed that the activated coastal waste of the Z. marina plant could be utilized as an effectual and promising biosorbent substance for the remediation of an aquatic environment contaminated with manganese ions.

“…The carboxylated jute stick-derived activated carbon's maximum adsorption capacity for Pb 2+ was reported to be 2079 mg/g (Aziz et al 2019 ). Several studies used the rice husk-based adsorbents in removing Pb 2+ ions (Abdel-Ghani et al 2007 ; Amen et al 2020 ; Arabahmadi and Ghorbani 2017 ; Feng et al 2004 ; Fooladgar et al 2019 ; Gupta et al 2009 ; Janyasuthiwong et al 2015 ; Kamari et al 2019 ; Mahmoud et al 2020 ; Masoumi et al 2016 ; Masoumi et al 2016 ; Naiya et al 2009 ; Nnaji et al 2017 ; Shi et al 2019 ; Sun et al 2019 ; Wang et al 2018 ; Zulkali et al 2006 ), which showed the maximum adsorption capacity in the range of 5.7–1665.0 mg/g (Table 4 ). The rice husk ash showed an adsorption capacity of 91.7 mg/g, and the maximum removal efficiency was 99.3% (Naiya et al 2009 ).…”

“…The magnetic rice husk biochar reported the maximum adsorption capacity of 148 and 129 mg/g, respectively (Sun et al 2019 ; Wang et al 2018 ). A low-cost amine-functionalized nanocomposite adsorbent was prepared by extracting amorphous silica from rice husk (Kamari et al 2019 ). The adsorbent's surface area and pore volumes were 695 m 2 /g and 0.65 cm 3 /g, respectively.…”

The presence of lead compounds in the environment is an issue. In particular, supply water consumption has been reported to be a significant source of human exposure to lead compounds, which can pose an elevated risk to humans. Due to its toxicity, the International Agency for Research on Cancer and the US Environmental Protection Agency (USEPA) have classified lead (Pb) and its compounds as probable human carcinogens. The European Community Directive and World Health Organization have set the maximum acceptable lead limits in tap water as 10 µg/L. The USEPA has a guideline value of 15 µg/L in drinking water. Removal of lead ions from water and wastewater is of great importance from regulatory and health perspectives. To date, several hundred publications have been reported on the removal of lead ions from an aqueous solution. This study reviewed the research findings on the low-cost removal of lead ions using different types of adsorbents. The research achievements to date and the limitations were investigated. Different types of adsorbents were compared with respect to adsorption capacity, removal performances, sorbent dose, optimum pH, temperature, initial concentration, and contact time. The best adsorbents and the scopes of improvements were identified. The adsorption capacity of natural materials, industrial byproducts, agricultural waste, forest waste, and biotechnology-based adsorbents were in the ranges of 0.8–333.3 mg/g, 2.5–524.0 mg/g, 0.7–2079 mg/g, 0.4–769.2 mg/g, and 7.6–526.0 mg/g, respectively. The removal efficiency for these adsorbents was in the range of 13.6–100%. Future research to improve these adsorbents might assist in developing low-cost adsorbents for mass-scale applications.
