Abstract This study focused on the use of a fix-bed column in removal amoxicillin from an aqueous solution by application silver nano-based adsorbents. The nanoparticle and nanocomposite were produced green synthetic approach. Column adsorption was performed at flow rate 5.88 mL/min, bed height (5.0–7.0 cm), concentration 20–40 mg/L. Adsorption data fitted to Thomas, Adams-Bohart, Yoon-Nelson m...

Nanotechnology is an emerging science offering promising models of decontamination. The present experimental design is to synthesize novel nanoparticles of Iron and Nickel oxides to be used as catalysts for in situ removal of different pollutants discharged from various industries. Particle size of synthesized iron and nickel oxides nanoparticles was characteristic of ~28-36 nm and ~48-56, resp...

Three kinds of inorganic alkali are introduced into tetraethylenepentamine (TEPA)and polyethyleneimine (PEI)-modified MCM-41 as the CO2 adsorbents. FT-IR and TGA are used to characterize the surface groups and the thermal stability of adsorbents. Chemical titration method is used to measure the alkali amounts of adsorbents. Thermo-gravimetric analysis with 10% CO2/90% N2 as the simulated flue g...

In this review, adsorbents used in wastewater treatment and their technical feasibilities are reviewed. Adsorbents are classified as natural adsorbents, and the adsorbents obtained from industrial and agricultural wastes. They all were compared with each other condensing the metal binding capacities, costs and metal removal performances in waste water treatments. Although commercial activated c...

Copper, zinc, and cerium oxide adsorbents supported on alumina were used to remove silane gas (SiH4). The adsorbents were prepared using a coprecipitation method and characterized by the inductively coupled plasma mass spectrometry, X-ray powder diffractometer, and Brunauer-Emmett-Teller method (BET). The silane removal efficiency and adsorption capacity of the adsorbents were investigated in t...

In the present article, the suitability of activated carbon and other alternative adsorbents for wastewater treatment has been reviewed. It is evident from literature survey of last 20-25 years that researchers have gained success to some extent in developing inexpensive adsorbents for water pollution control utilizing naturally available and waste materials. However, still there is a need to f...
