Spent coffee grounds were evaluated for adsorption
efficiency in the removal of pesticide paraquat from its aqueous
solutions. The influence of the adsorbent mass, agitation time,
paraquat concentration and pH have been investigated in the batch
sorption mode. Adsorption capacity (mg/g) has been found to be
27.87 ± 1.57 mg/g, while the removal efficiency has resulted of 32.25
± 1.79 %. Adsorption rate was found to be very fast, whereby the
time required for equilibrium adsorption occurred within first 20
minutes. The process behavior was predicted using the second-order
kinetic model. On the basis of the observed data, further process
optimization may be greatly facilitated, thus it is considered that
coffee waste may be exploited well for pesticides removal purposes.
