Adsorption/bioadsorption of phthalic acid, an organic micropollutant present in landfill leachates, on activated carbons

► Phthalic acid adsorption is governed by dispersion and electrostatic interactions. ► The phthalic acid adsorption process is highly dependent on the solution pH. ► The presence of microorganisms during adsorption increases the adsorption yield. ► Phthalic acid removal varies as a function of the natural water type.
