مستخلص المنشور

The widespread use of pesticides leads to considerable attention for pesticide detection and removal.
Therefore, in the first part of this work, a simple and facile solid phase extraction (SPE) procedure for
separation of malathion from soil and water samples, has been established. Malathion was recovered at a
pH of 2.0–3.0 with limit of detection (LOD) of 0.026 ng L1. While in the second part, the kinetics of the
batch adsorption removal of malathion from aqueous solutions was investigated. Results showed that
malathion adsorption onto activated carbon followed second order kinetics models most appropriately
with adsorption capacity of 32.1 mg g1.
