“…Other physicochemical properties should indicate the characteristics of the material in terms of its use as a filtering medium/aiding purification, which, apart from not interfering with the operation of the purification device, should not adversely affect the chemical parameters and physicochemical properties of the purified medium [Jucherski et al, 2017;Bus et al, 2022]. For newly identified phosphorus sorbents beyond the materials included in the review [Gubernat et al, 2020], consideration should be given to: biochars [Almanassra et al, 2021;Luo et al, 2022], silica nanoparticles prepared from rice husk ash [Nguyen 2022], cockle shell powder [Nayeem et al, 2023], eggshells and calcined eggshells [Park et al, 2022] agnetite/zirconium-comodified attapulgite (Fe/ZrATP) [Deng et al, 2023]. The basic properties of sorbents/filter materials include structural properties, i.e.…”

The paper presents physicochemical studies of nine reactive materials for removing phosphorus from wastewater and water. The materials under analysis are raw forms of marl and travertine along with their thermally treated forms at temperatures of 500 °C, 650 °C, 700 °C (travertine), 700 °C, 900 °C, 1000 °C (marl) and the commercial material Polonite ® . The scope of the research included morphological analysis and elemental composition, specific surface area, pore volume and diameter, losses on ignition and the amount of elements leached from materials. The results of the research allowed assessing the impact of physicochemical properties and thermal modification on the efficiency of phosphorus binding by these materials. All the tested sorbents show the highest calcium content among the elements with the ability to bind phosphorus. The size of the specific surface does not determine the efficiency of phosphorus retention by the tested materials; therefore it is advisable to study the mechanism of its binding. The thermal modification process, along with the increase in the treatment temperature, improves the regularity of marl and travertine structures, which also manifests itself in increasing the efficiency of phosphorus removal.

Water scarcity is the most imperative predicament that concerns the population. In this research, a roller kiln (RK) industrial solid waste was used in the adsorption of phosphate ions from aqueous solutions thus converting a waste to wealth through aiding in serving as a water treatment application. The RK waste was produced from an Egyptian factory with a flow rate of million tons/day. Surface characterization for this solid waste was performed including transmission electron microscopy (TEM), X-ray diffraction (XRD), X-ray fluorescence (XRF), Fourier transform infra-red (FTIR), zeta potential (ZP), and particle size distribution (PSD). Based on the kinetics and isotherm studies, the pseudo first order (PFO) kinetic model and Freundlich isotherm model were the best-fitted models with the experimental data as well as the Dubinin–Radushkevich isotherm model indicated that the adsorption type was physical. The attained experimental results were then optimized to attain the experimental conditions at which the optimum adsorption percentage was achieved using response surface methodology (RSM). The optimum percentage removal of phosphate ions 99.5 (%) was achieved at the following experimental conditions; pH 8, temperature = 25 °C, contact time = 9 min, initial phosphate ion concentration = 10 mg/L and adsorbent dose 0.5 = g/L.

This study demonstrated the feasibility of using zirconium dioxide nanoparticles (ZrO2 NPs) synthesixed using a hydrothermal technique for the removal of lead in aqueous solution. The physico-chemical characterization illustrated that the synthesized ZrO2 NPs have a non-uniform shape with an average size of 15 nm, surface area of 41.56 m2 g-1 and adsorption pore width of 3.06 nm. These findings revealed the potential use of ZrO2 NPs for chelating lead ions. The maximum lead adsorption capacity of ZrO2 NPs was obtained around 4.12 mg g-1 at adsorption conditions i.e., stirring speed of 200 rpm and contact time of 120 min. Thus, this method provides a number of advantages, including an efficient and cost-effective method for the removal of lead using ZrO2 NPs.
