Sewage sludge is the promising raw material for biosorbent preparation. In this work, we evaluated the heavy metals adsorption characteristics of alkali treated sewage sludge (ATSS) by equilibrium studies. The adsorption isotherms were fitted with Langmuir and Freundlich models. Comparing with untre[r]

7.1.2 Photoanodes with TiO 2 nanorods The Highly crystalline TiO 2 nanorods (NRs) with lengths of ~100-300 nm and diameters of ~20-30 nm were grown by J. Jui et al using the hydrothermal process with cetyltrimethylammonium bromide surfactant sol[r]
In this study, magnetite Zn/Al layered double hydroxide (LDH) composite has been synthesized through the chemical co–precipitation method. Raw water samples of Thu Duc and Tan Hiep water plant were also collected and analysed, they were used as the object to investigate dissolved organic compounds ([r]
In this work, the adsorption ability of β12 borophene towards some main harmful gases was investigated. The first-principles calculations were employed to obtain the adsorption configurations and the adsorption energies of CO, NO, CO2, NH3, and NO2 on 12 borophene. The vdW interactions are taken in[r]
