“…This can be attributed to the complexation of Cr(III) with negatively charged moieties formed as a result of hydrolysis of organic functionalities during NaOH treatment. Enhancement of Cr(III) removal by different biosorbents modified with NaOH solutions has been reported supporting the observations made in this research (Bishnoi et al 2007;Ranasinghe et al 2018). The highest Cr(III) removal was observed when the biosorbent was treated with 0.010 M NaOH solution (NWBF2).…”

“…In this context, biosorption, which uses naturally available substances, has become an economically and environmentally friendly approach for the removal of heavy metal ions from 1 3 115 Page 2 of 11 contaminated water although this method has not been much used in large-scale industrial setting at present (Ranasinghe et al 2018). Unlike in chemical treatment, biosorbents contain a vast number of organic compounds with many different types of functionalities which would attract heavy metal ions through complexation, in addition to other modes of mass transfer, such as ion exchange, transfer to micro-or macropores, and interparticle diffusion (Barakat 2011).…”

Adsorption behavior of chromium on Muthurajawela peat (Priyantha et al 2015), vesicular basalt (Alemu et al 2018), fired brick particles (Priyantha and Seneviratne 2007), peel of jackfruit (Ranasinghe et al 2018), palm kernel fiber, and coconut husk (Ju and Ezuma 2014) has been investigated. Organic biosorbents have more advantages, such as low cost, high efficiency, minimum chemical use, low processing conditions, low energy technology, and high metal recovery (Richards et al 2019) as compared to synthetic materials,.…”

“…Modified surface thereafter would behave as a new adsorbent, showing different characteristics resembling those of the modifying agent. Common modifying agents include NaOH, HCl, CH 3 COOH, HNO 3 , EDTA, citric acid, and sodium dodecyl sulfate (SDS) (Ramana et al 2012;Ranasinghe et al 2018).…”

Performance characteristics of peel of Artocarpus nobilis fruit can be enhanced by the treatment of the biosorbent with aqueous NaOH solutions under stirred conditions, followed by thorough washing of the treated biosorbent with water. A series of experiments performed within a wide range of solution pH demonstrates that the optimum pH for Cr(III) removal is pH 5.0, while it is 2.0 for Cr(VI) by peel of Artocarpus nobilis fruit after treatment with aqueous NaOH solutions of concentrations varied from 0.0050 to 0.15 M. Adsorption of Cr(III) and Cr(VI) from individual aqueous solutions on the above biosorbent treated with 0.010 M NaOH solution, which provides the highest extent of removal of 4.89 × 10 3 mg kg −1 (pH = 5) and 4.94 × 10 3 mg kg −1 (pH = 2), respectively, follows pseudo-first-order kinetics at the ambient temperature of 27.5 °C when the concentration of adsorbate concentration is kept relatively constant. The order of the reaction is unchanged when the solution temperature is increased up to 40.0 °C for Cr(III) although the reaction becomes pseudo-second order for Cr(VI). Further, the energy of activation for adsorption of Cr(III) is determined to be 66.82 kJ mol −1 , suggesting a strong attraction between the adsorbate and the biosorbent. Application of the intraparticle diffusion model to kinetics data within the early stages of the adsorption process of Cr(III) suggests that boundary layer-retarded diffusion be valid at both solution temperatures, while no retardation be possible for Cr(VI) at the warmer temperature.Keywords Chromium species · NaOH treatment · Biosorbent · pH effect Abbreviations NWBF1 0.005 M NaOH-treated peel of Artocarpus nobilis fruit NWBF2 0.010 M NaOH-treated peel of Artocarpus nobilis fruit NWBF3 0.020 M NaOH-treated peel of Artocarpus nobilis fruit NWBF4 0.050 M NaOH-treated peel of Artocarpus nobilis fruit NWBF5 0.100 M NaOH-treated peel of Artocarpus nobilis fruit NWBF6 0.150 M NaOH-treated peel of Artocarpus nobilis fruit MB Methylene blue * N.

“…The activated carbon is the top sorbent matter utilized in biosorption practice owing to great physicochemical structural properties. However, the problems like high manufacturing expense and low regeneration capacity restrain the influential use of activated carbon in the large-scale heavy metal decontamination applications [ 8 , 9 ]. In recent years, due to their properties such as high abundance, biodegradable, low cost, renewable, high regeneration capacity, environmentally friendly, and high yield, the utilization of natural biological wastes instead of activated carbon as a sorbent matter has become an attractive area of research [ 10 , 11 ].…”

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.
