The very serious problem in developing countries has become the presence of the arsenic
contamination in the water for the public health. Still, millions of people in their daily lives are
highly dependent on groundwater containing high levels of arsenic, as well as, in drinking water,
which causes excessive exposure to this toxic element, due to the high cost and lack of watertreatment infrastructures. The maximal allowed concentration (MAC) for As(V) in water
decreased from 50 to 10 μg/l, by considering the harmful effects of arsenic on the environment
and human health. In order to achieve the established rigorous requirements, it is necessary to
develop new materials and design new forms of adsorbents that can reduce the concentration of
arsenic in drinking water. Therefore, in this study, the target was to synthesize magnetite/3Dprinted wollastonite hybrid sorbent that was used to remove As(V) from aqueous solutions. 3Dprinted wollastonite was obtained using the 3D-printing ...technique from
methylhydrocyclosiloxane and calcium carbonate as precursors. Synthesis of adsorption
material was carried out by depositing magnetite from an iron(II)-sulfate solution by potassium
hydroxide on 3D-printed wollastonite. Characterization of the obtained material was performed
using FTIR and SEM. An investigation of the sorption properties of hybrid adsorbents was
carried out for As(V) removal - one relative to the starting pH value of the solution, the
adsorbent mass and the temperature and the adsorption time. Determination of adsorption
parameters was performed by applying Langmuir, Freundlich and Dubinin-Radushkevich
equations. Determination of kinetics and adhesion parameters at three different temperatures
enabled the calculation of thermodynamic and activation parameters of the adsorption process,
which contributed to a better understanding of the adsorption mechanism. Also, based on the
results, it was noticed that the highest adsorption capacity of the mentioned material for arsenic
ions at a temperature of 45 °C. The compact filter presented in this report should serve well as a
small-scale water-purification unit that can be easily carried to any site having water
contaminated with arsenic
