%X A microwave-assisted extraction was optimized for the evaluation of
persistent organic pollutants in liquid fertilizer samples. The extraction
process was defined by a 2<sup>3</sup> factorial design. The parameters (temperature
and sample and solvent volume) were optimized through the response surface
methodology (RSM). The data for the study were based on injection of a mix of
organochlorine pesticides. In optimized conditions, the microwave-assisted
extraction was carried out at 70¡æ for 10 minutes using 10 mL of sample and 10
mL of solvent. This study was accomplishment to evaluate the statistical
influence of parameters: temperature, solvent volume and sample volume in the
microwave-assisted extraction of organochlorine contaminants present in
biofertilizer samples obtained from liquid humus and consequently to define the
best conditions of process.
