Adsorption of Co(II) from the simulated solution by zeolite NaX derived from rice husk ash

Carmine Adsorption from Aqueous Solution by Crosslinked Peanut Husk

To observe the feasibility of the removal of carmine, peanut husk, an agriculture by-product, was crosslinked with epichlorohydrin in alkaline medium and used for adsorption of carmine from aqueous solution. Batch experiments were carried out to study the effects of various parameters such as initial pH, contact time, adsorbent dosage and initial carmine concentration, as ...

Adsorption of Acetone Vapors by SBA-16 and MCM-48 Synthesized from Rice Husk Ash

Silica was extracted from agriculture waste rice husk ash (RHA) and was used as the silica source for synthesis of RMCM-48 and RSBA-16. An alkali fusion process was utilized to separate silicate supernatant and the sediment effectively. The CTAB/Si and F127/Si molar ratio was employed to control the structure properties of the obtained RMCM-48 and RSBA-16 materials. The N2 adsorption-desorption...

Adsorption of Cu(II) from Aqueous Solution on Fly Ash Based Linde F (K) Zeolite

The work focuses on the removing of Cu(II) from aqueous solution by Linde F(K) zeolite. The zeolite is synthesized from fly ash by hydrothermal process. The adsorption experiments discuss several factors including the optimal solution pH, zeolite dosage, adsorption temperature, adsorption kinetics and adsorption isotherm equation. The results show that, the optima...

Ultrasonic and conventional synthesis of NaA zeolite from rice husk ash

Biosorption of Fe(II) and Mn(II) Ions from Aqueous Solution by Rice Husk Ash

Rice husk ash (RHA), an agricultural waste, was used as biosorbent for the removal of Iron(II) and Manganese(II) ions from aqueous solutions. The structural and morphological characteristics of RHA and its elemental compositions before and after adsorption of Fe(II) and Mn(II) were determined by scanning electron microscopic (SEM) and X-ray fluorescence (XRF) analyses. Batch experiments were ca...
