“…Also, the peak of 1,035 cm -1 , corresponding to the stretching of carbon-carbon bond and carbon-oxygen bond, was slightly reduced, which provides further information in heavy metal sorption. These results were in agreement with the data obtained by other authors [11,[37][38]. The decreasing amplitude among different functional groups after metal sorption was roughly similar and this has suggested that both of the groups played a significant role on metal biding.…”

“…In addition, algae with a high tolerance to one kind of heavy metal may serve as the bioadsorbent to this metal. Accordingly, being a renewable natural biomass, algae with ample functional radicals, including amino, carboxyl, hydroxyl, and carbonyl, has attracted increasing attention in the removal of heavy metals from wastewater as a bioadsorbent [11][12]. Yalcin et al found that dried marine brown macro algae Cystoseirabarbata showed the highest adsorption capacity for Pb with the highest calculated equilibrium adsorption quantity (q e ), compared to Cd and Ni [13].…”

With the dynamic development of industrialization and urbanization, the entrance of heavy metals from industrial discharge, domestic sewage, and atmospheric deposition into natural water, even at low concentrations, has induced a series of potential impacts on both aquatic ecosystems and human health [1]. Being an essential part of primary productivity, algae show high sensitivity to various heavy metals such as Pb [2]. Consequently, algae serve as a testing model to evaluate the quality of freshwater and estimate the toxicity of pollutants. By now, numerous studies have illustrated that most heavy metals, including Cd, Pb, Cu, and Ni, can interfere with the photosynthesis and enzymatic metabolism of algae, which results in growth inhibition and even death. Choudhary et al. found that Pb, Cu, and Zn could generate reactive oxygen species (ROS) and attack biomolecules within the cells, further leading to irreversible adverse effects on Spirulina [3]. The analogous toxic mechanism of Cu on the green Pol. J. Environ. Stud. Vol. 26, No. 3 (2017) AbstractThe link between the acute toxicity of heavy metals on algae and the bioadsorption capacity of heavy metals by algae has seldom been reported. In the present study, an acute toxicity experiment was carried out to assess the toxic effects of Pb, Cu, and Cd for Chlorella sorokiniana, and the 96 h IC 50 values were 0.249 mg/L, 0.485 mg/L, 46.108 mg/L, and 21.00 mg/L for Cu, Cd, Pb (total), and Pb (free ion), respectively, which implied that Chlorella sorokiniana showed high tolerance to Pb compared to Cu and Cd. Pb distribution analysis indicated that 73.40% to 98.15% of free Pb ions were accumulated on the algae cell wall to avoid further intracellular accumulation, resulting in irreversible metabolic disorders. Then the adsorption capacity of Chlorella was explored. It could be found that the Langmuir model (the R 2 were 0.988 and 0.962 for living and lifelss cells, respectively) was fit to explain the adsorption equilibrium data and the q e calculated by this model were 1.54 and 2.97 mg /10 10 cells for living and lifeless cells, respectively, which was consistent with the experimental result. In the competitive adsorption, Chlorella exhibited a greater affinity for Pb with the higher removal rate compared to Cu and Ni. Therefore, the renewable Chlorella sorokiniana and its dramatic resistance to Pb may serve as a potential biosorbent for Pb in the future.

Massive industrialization and urbanization of civilization during the last few decades have made a thrust in heavy metal pollution in various water bodies. In past, various kinds of conventional metal ion remediation technologies, such as cementation, osmosis, reverse osmosis, ultrafiltration, etc., have been practised. However, most of these technologies are quite expensive, and lead to the generation of secondary chemical sludge. However, biosorption of heavy metal ions is significantly inexpensive and an eco-friendly technology. Among the series of heavy metals, zinc has gained the significant interest due to its toxicity and easy availability in water bodies. Biosorption of zinc in liquid phase by living, nonliving, conventional and non-conventional biosorbents has been practised extensively in the past. This literature review focuses on the recent trends practised in the field of biosorption of zinc from liquid phase. The present work provides deep insight into various aspects of biosorption of zinc by different mechanisms of biosorption, bioaccumulation, isotherm, kinetic and mechanistic modeling. An exhaustive comparison among different sorts of biomasses has also been given in the present work to enlist all the milestones of biosorption.

“…This approach generates cost savings while simultaneously solving a waste disposal problem. Various bacteria, yeast, fungi, micro and macroalgae, and agricultural waste products are shown to be useful in removing metal ions [3][4][5][6][7][8][9]. However, uptake capacities differ between biosorbents, given different cell wall structure as well as availability and accessibility of functional groups for metal uptake [10].…”

Graphical abstract Short descriptionReduced kinetic and equilibrium uptake of copper on formaldehyde crosslinked Sargassum sp. seaweed from low concentration solutions suggested interference effect from ammonium ion cosolute. PeerJ Preprints AbstractSargassum sp., a marine brown macroalgae, is an efficient sorbent for various heavy metals at high concentrations. However, the efficiency at which seaweed removes heavy metals from dilute solutions and the effect of ammonium on metal removal is not well understood; an issue of importance given the ubiquity of nitrogenous compounds in the environment arising from various surface runoffs. Herein, the effect of ammonium on copper removal (at trace to low concentration) by formaldehyde crosslinked Sargassum sp. (treated SW) was studied. Due to high copper background, equilibrium sorption experiments was inconclusive concerning treated SW's ability in removing copper (<1000 ppb), but rapid copper sorption observed in kinetic experiments suggested potential feasibility of the process. Within initial copper concentration of 4 to 20 ppm and pH 2 to 5, experiments revealed that, above a threshold concentration of [NH4 + -N] of 50 ppm, ammonium impede copper update on treated SW in a concentration dependent manner. Specifically, sorption kinetics slowed, and uptake capacity decreased with increase in [NH4 + -N] from 0 to 2500 ppm. Collectively, beyond demonstrating that treated SW could remove copper from dilute solutions, revelations that ammonium reduced copper sorption highlighted the importance of accounting for the effect in data interpretation and modelling.
