Heavy metals are present in wastewater generated by industrial sectors, posing a threat to the environment, including surface and groundwater resources. With this in mind, there is a growing interest in finding alternative yet effective methods of removing heavy metal ions from industrial wastewater. Sorption is one of the techniques being readily applied due to the simplicity, high efficiency, production of small amounts of sludge, low investment, and the feasibility of the process over a wide range of pH and temperature. This paper deals with the treatment of industrial wastewater from electropolishing of stainless steel containing high concentrations of metal ions Fe(III), Cr(III), Ni(II), and Cu(II). Taking into account the effectiveness, availability and applicability of biosorbents for acidic wastewater, orange peels, algae, Eclipta alba, and eggshells were selected for the study. Sorption tests were carried out for Eclipta alba and the results obtained showed a best fit for the second-order kinetic model (R2 > 0.99) and the Langmuir isotherm model (R2 > 0.99). Maximum adsorption capacity was 17.92 mg/g for mixture of metal ions. The potential use of dried and calcinated eggshells was established. Both materials achieved a high removal rate of over 95%. Iron and chromium are removed from the solution first (about 100% and 90%, respectively), followed by nickel and copper ions. FT-IR and SEM with EDS measurements used to characterize materials, together with laboratory tests using real industrial effluent, made it possible to determine their mechanism of action. Specific surface area was determined for all tested materials and the values were: 1.63, 0.15 and 5.15 m2/g for Eclipta alba, dried eggshells and calcinated eggshells, respectively. The results provide grounds for optimism in the application of selected materials for industrial wastewater treatment.

“…So, for high removal efficiency, more in-depth experiments on the natural zeolites from different deposits with specific characteristics and their pretreatment are necessary. The aims of this paper are: (1) to characterize the thermally treated zeolitic tuff from the Racos , quarry; (2) to investigate the influence of thermal treatment, contact time, and initial concentrations of metals in solution on the capacity of natural zeolite with two different particle sizes to remove Cu, Cd, Cr, Ni, Zn and Pb from multicomponent contaminated aqueous solutions; (3) to evaluate the contribution of ion exchange and chemisorption processes to the total immobilization of heavy metals in zeolites.…”

Increased concentrations of heavy metals in the environment are of public health concern, their removal from waters receiving considerable interest. The aim of this paper was to study the simultaneous adsorption of heavy metals (Cu, Cd, Cr, Ni, Zn and Pb) from aqueous solutions using the zeolitic volcanic tuffs as adsorbents. The effect of thermal treatment temperature, particle size and initial metal concentrations on the metal ions sorption was investigated. The selectivity of used zeolite for the adsorption of studied heavy metals followed the order: Pb > Cr > Cu > Zn > Cd > Ni. The removal efficiency of the heavy metals was strongly influenced by the particle sizes, the samples with smaller particle size (0–0.05 mm) being more efficient in heavy metals removal than those with larger particle size (1–3 mm). Generally, no relevant changes were observed in heavy metals removal efficiency for the treatment temperatures of 200 °C and 350 °C. Moreover, at a higher temperature (550 °C), a decrease in the removal efficiencies was observed. The Cd, Zn, Cu, Cr, Zn and Ni sorption was best described by Langmuir model according to the high values of correlation coefficient. The pseudo-first-order kinetic model presented the best correlation of the experimental data.

Land degradation and soil contamination have become global problem due to irresponsible anthropogenic activities and the overutilization of natural resources by humans. Land degradation and contamination due to toxic heavy metals have adversely impacted not only crop productivity but also the overall environmental health of our planet. Mitigation and management of polluted land are urgently required to achieve the goal of sustainable development because of the continuous human population explosion. In recent years, the biodiversity under phytoremediation is gaining scientists' attention for utilizing polluted lands and obtaining a bio‐based economy aimed at economically valuable and nonedible native plants. In the present review, we have focused on the biodiversity prospecting and phytoremediation potentials of economically important native plants, which may open up new horizons for sustainable development and redevelopment of polluted land sites.
