Abstract Natural adsorbents are a good alternative to remove antibiotic residues from wastewater. In this study, the adsorption capacity of sulfamethoxazole (SMX) onto sugarcane bagasse (SB) and corn cob (CC) in continuous fixed-bed was compared. Brunauer Emmett Teller, Fourier transform infrared (FTIR), Boehm titration, point zero charge (pH pzc ) were used characterize both adsorbents. The (q...

The Thomas model is the most common equation to describe dynamics of fixed-bed adsorption columns. However, its parameters’ validity strongly depends on region breakthrough curve considered for data fitting. A rigorous analysis based different error functions was carried out determine accuracy both linear and non-linear forms model. proved be more robust less susceptible experimental error, wit...

Two laboratory tests were carried out to verify the suitability of an Italian commercial biochar as adsorbing material. The chosen contaminant, considered dissolved in groundwater, was As. circular economic concept demands use such waste Its has been studied recent years on several contaminants. possibility using efficient material at low cost could help low-impact technologies like permeable r...

Water pollution and the lack of access to clean water are general global problems that result from expansion industrial agricultural activities. Petroleum refinery wastewaters consider as a major challenge environment their treatment is mandatory. The present work concerns with removal chemical oxygen demand (COD) petroleum wastewater taken Iraq's Al-Diwaniyah plant by using an activated carb f...
