A novel and very simple microextraction approach for pre-concentration and direct solid phase spectrophotometric measurement has been developed for the determination of chromogenic analytes. The model analyte to assess this approach was the chromophore malachite green (MG). The analyte was extracted from water samples onto a small rotating disk made of Teflon containing a sorbent phase of polydimethylsiloxane (PDMS) on one of its surfaces. We refer to the extraction procedure as rotating disk sorptive extraction (RDSE). After extraction, the sorbent phase with the concentrated analyte was separated from the Teflon disk and used directly for MG determination by solid phase spectrophotometry at 624nm, without the necessity of a desorption step.Chemical and extraction variables such as concentration of sodium sulfate, pH, disk rotational velocity, extraction time, and temperature were studied in order to establish the best conditions for extraction. Under optimum conditions, the extraction of MG was carried out in 18min and 90min, for sample volumes of 100mL or 1000mL, respectively. The detection limit, based on three times the standard deviation of the blank phase (3σ b ), was 1.4μgL −1 , and the repeatability, expressed as relative standard deviation (RSD), for 20μgL −1 MG was 8.1%. This study also applied the method to real samples, obtaining quantitative recovery (mean recovery of 99.3%).The PDMS phases could be reused after desorbing the MG into methanol for 3h. Replacement of the PDMS film onto the disk is very easy and low cost.
