Performance evaluation of organoclays for the amoxicillin retention in a dynamic context

The hydraulic conductivity of diverse organoclays was determined through percolation experiments and compared to a raw Na-montmorillonite (Na-Mt). incorporation surfactants even at low content drastically changes the with large increase about two order magnitude in contrast that Na-Mt (10?12 m s?1). Batch kinetics equilibrium adsorption confirmed proper affinity zwitterion antibiotic: amoxicillin (AMX) which quickly adsorbed (at time below 30 min) amounts (up 1.4 × 10?3 mol g?1). However, conditions, significant permeability led short interaction between pharmaceutical. In for it took age get only one drop AMX, leachates, resulting organoclays, were collected 10 min, not enough sufficient ensure removal an antibiotic concentration reduced by 5–80% initial solution.
