Abstract:
In this work, a method for extraction of Cd in water by dispersive liquid-liquid
microextraction (DLLME) was developed. The sodium diethyldithiocarbamate (DDTC)
was used as a chelating reagent. The Cd-DDTC complex was extracted and detected by
UV-Visible spectrometry. The extraction conditions i.e. concentration of chelating reagent,
pH of solution, volume of extraction solvent and disperser solvent, extraction time and
salting out effect were optimized. Under the optimum condition, the calibration graph was
linear in the range of 30-130 μg/L with R2 of 0.9982 The limit of detection (LOD) and
limit of quantitation (LOQ) were 4.2 μg/L and 14.2 μg/L, respectively. The relative
standard deviation for repeatability study was less than 10 %. The recoveries were in the
range of 81.29-108.74%. The proposed method was applied for determination of Cd in
water samples collected from Map Ta Phut industrial estate, Rayong province.
