Preparing a sample for analysis is a crucial step of many analytical procedures. The goal of sample preparation is to provide a representative, homogenous sample that is free of interferences and compatible with the intended analytical method. Green approaches to sample preparation require that the consumption of hazardous organic solvents and energy be minimized or even eliminated in the analytical process. While no sample preparation is clearly the most environmentally friendly approach, complete elimination of this step is not always practical. In such cases, the extraction techniques which use low amounts of solvents or no solvents are considered ideal alternatives. This paper presents an overview of green extraction procedures and sample preparation methodologies, briefly introduces their theoretical principles, and describes the recent developments in food, pharmaceutical, environmental and bioanalytical chemistry applications.

In this paper, the application of sodium dodecylsulfate-coated Fe 3 O 4 nanoparticles as an adsorbent was evaluated for the extraction and preconcentration of trace amounts of terbinafine hydrochloride in biological fluids before its determination by high-performance liquid chromatography with ultraviolet detection. Effects of various parameters on the extraction efficiency such as pH of solution, amount of sodium dodecylsulfate surfactant, extraction time, and desorption conditions were studied and optimized. Under the optimal conditions, the calibration curve was linear in the range of 2.5 to 500 μg L À1with the correlation coefficient of 0.9998. Moreover, the calibration graphs were linear in the range of 5 to 500 μg L À1 (seven standards)for both urine and plasma samples and the limits of detection were found to be 0.3, 0.7, and 1.5 μg L À1in aqueous, urine, and plasma samples, respectively. Also, the percent of relative standard deviation (RSD%) based on three replicate determinations was in the range of 0.9% to 6.8%. Finally, the proposed method was successfully applied for the extraction of terbinafine from real samples, and satisfactory results were obtained.

“…Sedangkan analisis menggunakan ICP OES belum banyak digunakan karena biaya yang cukup L 24107-39 mahal tetapi memiliki kelebihan dalam menganalisis multilogam dan memiliki range linear yang besar serta limit deteksi yang kecil (Naschan, 2017). Logam Pb yang berada didalam sampel air memiliki kadar yang sangat rendah (trace metals) (Yuniar & Nuraini, 2019) (Destiarti & Zaharah, 2015) (Sari et al, 2017), kadar tersebut lebih rendah dari baku mutu lingkungan (Umum, 2002), oleh karena itu diperlukan suatu pengembangan metode analisis logam Pb yang dapat diandalkan, sensitif dan tepat untuk menentukan logam yang sangat kecil dengan akurasi yang tinggi dan biaya yang murah (Gugushe et al, 2019) (Faraji et al, 2016).…”

Prekonsentrasi logam timbal (Pb) telah dilakukan menggunakan ultrasonik dengan metode Spektofotometer Serapan Atom (SSA)-nyala. Teknik prekonsentrasi ini dilakukan dengan dengan tujuan untuk mendeteksi logam Pb di dalam sampel air yang memiliki kadar yang sangat rendah (trace metals). Prosedur yang dilakukan pada penelitian ini adalah sampel air ditambahkan resin Dowex 50WX2-200 kemudian dilakukan sonikasi didalam ultrasonik untuk prekonsentrasi dan ekstraksi setelah itu dilakukan proses filtrasi, resin kemudian ditambahkan eluen HNO 3 1 M untuk mengelusi logam Pb, hasil elusi kemudian di ukur dengan SSA. Kondisi optimum yang didapatkan dalam penelitian ini antara lain waktu prekonsentrasi 20 menit, volume eluen 10 ml dan pH 2. Parameter variasi volume sampel didapatkan volume optimum pengujian ini adalah 50 ml dengan faktor pengayaan 5. Metode ini cukup handal dibuktikan dengan pengujian CRM Metal ERA-697 untuk akurasi dan presisi dengan hasil yaitu 92.07 % untuk akurasi dan dan RSD 3.6% (n=3) untuk presisi, nilai akurasi yang diperoleh memenuhi batas keberterimaan menurut AOAC yaitu 70% -125% dan presisi dengan % RSD lebih kecil dari CV Horwitz yaitu 14%. Teknik prekonsentrasi logam Pb menggunakan ultrasonik dengan metode SSA ini dapat dimanfaatkan dalam implementasi pengujian logam Pb dalam air dengan teknik yang cukup mudah, cepat dan akurat.
