Abstract: | Udara ambien merupakan udara bebas di permukaan bumi pada lapisan troposfer yang dihirup oleh makhluk hidup. Metode pengukuran H2S udara ambien dilakukan dengan memodifikasi dari metode SNI 8605:2018. Gas hidrogen sulfida yang diserap di dalam midget impinger direaksikan dengan pereaksi N,N dimetil-p-fenilendiamina dan ferri klorida yang membentuk senyawa kompleks yang berwarna biru diukur pada 670 nm menggunakan spektrofotometer sinar tampak. Berdasarkan hasil penelitian diperoleh kadar larutan induk sebesar 2,0738 mg/L. Nilai validasi metode yang dilakukan memenuhi persyaratan parameter linearitas, isaran, IDL, LOD, LOQ, MDL, presisi repeatability, presisi internal reproducibility, akurasi, ruggedness, robustness didapatkan memenuhi syarat validasi. Ambient air is the free air on the Earth's surface in the troposphere layer that is inhaled by living organisms. The method for measuring ambient air H2S was modified from the SNI 8605:2018 standard. Hydrogen sulfide gas absorbed in a midget impinger was reacted with N,N-dimethyl-p-phenylenediamine and ferric chloride to form a blue-colored complex compound, which was measured at 670 nm using a visible spectrophotometer. Based on the research results, the concentration of the stock solution was 2.0738 mg/L. The validation of the method met the required parameters of linearity, range, IDL, LOD, LOQ, MDL, repeatability precision, intermediate precision, accuracy, ruggedness, and robustness. |
