“…In addition, increasing the shaking rate to 150 rpm did not affect the removal percentages for all adsorbents. Increasing the shaking rate also had a positive impact on Pb 2+ ion adsorption, as has been reported previously in the literature (Murithi et al, 2012;Shaheen et al, 2016).…”

In this study, stable and radioactive lead removal from aqueous solution by adsorption using bentonite, zeolite and perlite minerals obtained from various locations in Türkiye was studied in batch experiments. The adsorbents were first characterized using X-ray diffraction (XRD), X-ray fluorescence (XRF), Fourier-transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM) and energy-dispersive spectroscopy (EDS), and then the physicochemical properties were determined. The effects of various factors that influence adsorption, such as solution pH, adsorbent dosage, contact time, initial Pb2+ ion concentration, temperature and shaking rate, were studied. The adsorption of Pb2+ was modelled using the Langmuir, Freundlich and Dubinin–Radushkevich isotherms. The adsorption capacities of the minerals for Pb2+ followed the order: bentonite > zeolite > perlite, and the maximum adsorption capacities were 131.6, 36.1 and 21.5 mg g–1, respectively. The adsorption data fit well with the Langmuir isotherm. The bonding of lead ions on the adsorbents was confirmed by XRF and FTIR analyses after the adsorption process. The adsorption of Pb2+ ions on the adsorbents was spontaneous and endothermic. The adsorption process took place by cation exchange in addition to electrostatic interaction. Furthermore, radioactive 210Pb2+ adsorption on bentonite, zeolite and perlite was studied, with the analyte being analysed using a liquid scintillation counter. It was seen that in addition to Pb(II) ions, these minerals also adsorbed the radioactive decay products of 210Pb, which were 210Po and 210Bi. The removal percentages of 210Pb were 95%, 38% and 30% and those of 210Po were 75%, 60% and 74% for bentonite, zeolite and perlite, respectively.

“…A basic requirement for the human utilisation of water is the ability to remove chemical and biological pollutants quickly and efficiently at low-cost. Over the years, a plethora of technologies have been developed and proposed for water purification, among them are aerobic and anaerobic microbial degradation, chemical oxidation, sorption, coagulation, membrane separation, electrochemical treatment, dilution, filtration, flotation, softening, hydrogen peroxide catalysis, and reverse osmosis (Shaheen et al, 2016;Awasthi et al, 2019). The sorption is confirmed as a superior technology for wastewater treatment because of its cost-effectiveness, simplicity of operation, high sorption capacity toward pollutants, etc.…”

As available at lowor zero-cost, agricultural and food industry waste biomass has great potential to be used for wastewater treatment. It has been shown that, with minimum of chemical or mechanical pre-treatment, waste biomass has great adsorption capacity for different heavy metals, organic and biological pollutants from both drinking and wastewater. Since biomass is a renewable resource that is generated daily as waste and requires storage, its inclusion in sustainable development and the circular economy would have multiple benefits for society as a whole. The use of waste biomass for wastewater treatment would have a positive environmental, energy and economic impact on a country's welfare, especially developing ones.
