“…This in turn requires samples to be diluted to within the working range. This narrow range was comparable to the optimized working range of 0.5–5 ppb by Nugraha et al, 2017 [ 15 ], also using HVG-AAS as the analytical instrument. Good linearity was achieved for iAs in this study with R 2 of better than 0.99.…”

“…124 These forms, arsenite and arsenate, can reduce trivalent (+3) and pentavalent (+5) As ions, leading to their accumulation in body fluids and tissues. 125 To monitor the level of As in water, various techniques such as inductively coupled plasma mass spectroscopy (ICP-MS), 126 hydride generation atomic absorption spectroscopy (HG-AAS), 127 and atomic fluorescence spectroscopy (AFS) 128 have been suggested in the last few decades. Moreover, the AuNP-based colorimetric sensors have also been reported in terms of As detection.…”

Gold nanoparticles (AuNPs) are useful nanomaterials as transducers for colorimetric sensors because of their high extinction coefficient and ability to change color depending on aggregation status. Therefore, over the past few decades, AuNP-based colorimetric sensors have been widely applied in several environmental and biological applications, including the detection of water pollutants. According to various studies, water pollutants are classified into heavy metals or cationic metal ions, toxins, and pesticides. Notably, many researchers have been interested in AuNP that detect water pollutants with high sensitivity and selectivity, while offering no adverse environmental issues in terms of AuNP use. This review provides a representative overview of AuNP-based colorimetric sensors for detecting several water pollutants. In particular, we emphasize the advantages of AuNP as colorimetric transducers for water pollutant detection in terms of their low toxicity, high stability, facile processability, and unique optical properties. Next, we discuss the status quo and future prospects of AuNP-based colorimetric sensors for the detection of water pollutants. We believe that this review will promote research and development of AuNP as next-generation colorimetric transducers for water pollutant detection.

Pemilihan program digesti sampel dengan microwave penting dilakukan untuk memperoleh hasil destruksi yang sempurna. Kesempurnaan destruksi sampel menentukan keberterimaan parameter verifikasi metode yaitu akurasi, presisi, linearitas dan sensitivitas. Penelitian ini bertujuan untuk memilih metode destruksi microwave dalam penetapan total arsenik dalam MP-ASI menggunakan AAS-HVG. Evaluasi dilakukan terhadap parameter verifikasi metode dan perbandingan dua program microwave dilakukan dengan uji t. Hasil penelitian menunjukkan bahwa program destruksi microwave pertama (P1) lebih baik daripada program microwave pembanding (P2) yang menghasilkan rata-rata recovery 84,79% hingga 104,57% untuk sampel bermatriks makanan dan 64,43% untuk sampel air. Presisi metode terpilih menghasilkan rata-rata RSD 6,63% hingga 13,41% untuk sampel bermatriks dan 4,66% untuk sampel air. Linearitas metode pada program terpilih menunjukkan R: 0,997 dengan koefisien variasi regresi Vx0: 4,24%, sedangkan batas deteksi dan batas kuantifikasi sebagai parameter sensitivitas berturut-turut 0,04 ng/g dan 0,12 ng/g untuk sampel bermatriks serta 0,01 ng/ml dan 0,02 ng/ml untuk sampel air. Metode penetapan kadar total arsenik dengan program microwave terpilih memenuhi syarat keberterimaan menurut uji verifikasi metode.
