“…The comparison of biosorption capacity of three biosorbents for Pb(II) with various biomasses is presented in Table 4. It was found to be comparable and higher than those of many corresponding sorbents in literature [27,28,34,36,37]. The maximum biosorption capacity range of biosorbents were 51.9−82.9 mg/g, which is 6-10 times higher when comparing with the previous similar research that used a Lipton tea leaves as a biosorbent [32].…”

“…The accessibility of more active sites and functional groups for biosorption of Pb 2+ ions resulted in high biosorption efficiency [26,27]. Afterwards, when biosorbent dosage increased from 3 g/l to 5 g/l the biosorption efficiency was decreased due to the overlapping or aggregation of active sites at higher dosages [27,34]. The biosorption efficiency of biosorbents were declined in the following order NP>EC>TL.…”

Due to its toxicity causing serious health problems, persistence in the environment and non-biodegradability, lead (Pb) is considered as one of the most harmful metals on earth. In this study, dried aquatic plants as sorbents including Nymphoides peltata (NP), Typha laxmannii (TL), and Eichhornia crassipes (EC) were examined and compared to discover the best biosorption for Pb. The effect of physical and chemical parameters including pH (2.0-5.5), sorbent dosage (1-5 g/l), metal concentration (20-100 mg/l), and contact time (~240 min) were investigated to determine the optimal condition for Pb(II) biosorption. As a result, the optimum pH, sorbent dosage, and contact time were 5.0, 1 g/l, and 120 minutes, respectively. Pb 2+ biosorption data were found to follow the Langmuir isotherm model while the kinetic biosorption data followed pseudosecond-order model. The maximum biosorption capacity from Langmuir model was calculated as 63.3, 82.9, and 51.9 mg/g for EC, NP, and TL, respectively. All the results showed that biosorption efficiencies of Pb(II) by different biosorbents were in following order NP>EC>TL.

“…A further increase in biosorbents dosages over 20 g L À1 did not lead to an appreciable increase of removal efficiencies (p > 0.05). This result could be explained that the overlapping or aggregation of active sites at higher dosage and decreasing in total sorbent surface area (Ghasemi et al, 2014;Kostic´et al, 2014). Therefore, the optimum biosorbent dosage was 20 g L À1 .…”

“…Fourier transform infrared spectroscopy (FT-IR) is often used to identify the surface groups of the adsorbents and to determine those groups in binding of metal ions (Lasheen et al, 2012;Kostic´et al, 2014).

Screening a new biosorbent with low cost and high efficiency from a native plant material is a key to the adsorption of heavy metal ions from wastewater. In this study, the potential of Phytolacca americana L. as a biosorbent for Pb(II) removal from aqueous solutions was investigated. Experiments were performed to evaluate the effect of biosorbent dosage, pH, initial Pb(II) concentration and contact time on the Pb(II) removal. The results indicated that the hydroxyl, carboxyl and amine groups may take part in Pb(II) binding. HNO 3 -modified P. americana (HPAL) showed a significant higher uptake capacity compared to original P. americana (PAL) (p < 0.05). A dose of 20 g L À1 of biosorbents in solutions with an initial pH of 6.0, an initial Pb(II) concentration of 30 mg L À1 and a contact time of 120 min resulted in the maximum Pb(II) removal efficiency. The Freundlich isotherm gave a better fit than the Langmuir isotherm revealed that the biosorption was potentially multilayer. Further, the adsorption kinetics followed a pseudo second-order model, which implied that the biosorption was mainly a chemisorption process. The thermodynamic properties showed that the Pb(II) adsorption onto the P. americana biomass was feasible, spontaneous and exothermic in nature. Both physisorption and chemisorption were involved in the biosorption of Pb(II) onto the surface of P. americana biomass through electrostatic interaction and ion exchange. Additionally, desorption studies revealed promising regeneration potential of these biosorbents. The present study showed that P. americana biomass could be used

Effect of the application of blackcurrant seed post-extraction residues (BS) enriched via biosorption with Zn(II), Mn(II) and Cu(II) was examined in field tests on maize. As a nominal dose (100%), 2.5 kg of zinc, 1 kg of manganese and 0.5 kg of copper per hectare, were applied. The preparation was applied, also, in higher doses (150%, 200%).Crop yield and quality were assessed and multielemental analysis of grains was conducted. Grain yield obtained for maize treated with different doses of micronutrients (7.3 and 7.2 Mg ha -1 for BS 100% and BS 200%, respectively) was higher than in control group (6.2 Mg ha -1 ) and similar to a commercial reference product (7.1 Mg ha -1 ).Bioavailability of micronutrients from BS was shown to be higher than from reference commercial fertilizer. The highest content of micronutrients delivered to plants was observed for groups fertilized with BS in nominal dose of micronutrients (1.79, 7.08 and 28.55 mg kg -1 for Cu, Mn and Zn, respectively). The content of each micronutrient was 5.6% (Cu) 12.1% (Mn) and 12.6% (Zn) higher than in untreated group and 8.9% (Cu) 9.7% (Mn) and 8.7% (Zn) higher than commercial reference micronutrient fertilizer. New biocomponents are cheap and biodegradable carriers of nutrients which can be released in controlled way.
