Abstract

A (PDMS)-coated stir bar was prepared for a glass jacket-free stir bar sorptive extraction (SBSE) configuration by adhesion technique for the extraction of triazine herbicides prior to quantification using a gas chromatography-flame ionization detector (GC-FID). A central composite design (CCD) was used in the optimization of extraction and desorption conditions. At optimum conditions, values of factors were set as pH 8.5, with no addition of NaCl, for 25 minutes of extraction time, and 24 minutes of desorption time. Under optimal experimental conditions, the proposed method has linear ranges at 0.1 – 100 µgL-1 with correlation of determination (R2), ranging from 0.9991 – 0.9995, respectively. The limit of detection (LODs) and limit of quantification (LOQs) of three triazines were found to be ranging from 0.015 – 0.023 µgL-1 and 0.047 – 0.060 µgL-1, respectively.

 

Keywords:  stir bar sorptive extraction, triazine herbicides, central composite design, partition coefficient

 

Abstrak

Bar berputar yang disalut dengan polidimetilsiloksana (PDMS) telah disediakan untuk pengekstrakan erapan bar berputar (SBSE) tanpa jaket kaca melalui teknik lekatan untuk dianalisa sebelum kuantifikasi racun herbisid triazin dengan menggunakan kromatografi gas-pengesan ionisasi nyala (GC-FID). Reka bentuk komposit berpusat (CCD) telah digunakan untuk proses pengoptimuman keadaan pengekstrakan dan nyahjerapan. Pada keadaan optimum, nilai faktor adalah pH 8.5, tanpa penambahan NaCl, 25 minit masa pengekstrakan, dan masa nyahjerapan 24 minit. Kajian berdasarkan julat kelinearan antara 0.1 – 100 µgL-1 telah mencapai kelinearan yang baik dengan pekali R2 di rekod antara 0.9991 – 0.9995. Had pengesanan (LODs) dan kuantifikasi (LOQs) bagi tiga jenis triazin tersebut masing- masing dihitung antara 0.015 – 0.023 µgL-1 dan 0.047 – 0.060 µgL-1.
