PREPARASI CONTOH UJI PROFISIENSI UNTUK IDENTIFIKASI SENYAWA KIMIA BERBAHAYA
Abstract: The sample of
proficiency test for hazard chemical compounds in organic and water sample has
been made to identify hazard chemical compounds. Here, various matrix was added
to these hazard chemical compound. The organic sample derived from organic
waste added with dichloromethane as the solvent, undecane 100 µl/mL,
1,2-dimethylbenzene 12 µl/mL, dieselÂ
100 µl/mL and tributhyl phosphate 10,02 µg/mL, whereas water sample
derived from water waste added with
magnesium sulfate heptahydrate 120 µg/mL, sodium carbonate anhydrous 106
µg/mL, sodium sulfate anhydrous 284 µg/mL, calsium chloride dyhidrate 222 µg/mL, dikhloromethane 2,5
µl/mL, polyethylene glycol 505,4 µg/mL, 3,5 dihydroxytoluene 10,05 µg/mL and
α methyl-α-propyl succinimide 10,01 µg/mL. Hazard chemical compounds that being added are Bis (3-methylbutyl)
ethylphosphonate 10,04±0,31 µg/mL, Bis (2-chloroethyl) methylamine 20,59±0,14 µg/mL for organic sample and
Pinacolyl methylphosphonate 9,80±0,18 µg/mL and Triethanolamine 14,84±0,10
µg/mL for water sample. Homogeneity
and stability are determined quantitatively using GC-FPD (P-mode) and GC-FID with calibration
curve using internal standard dibuty butylphosphonate, 2,6-dimethylphenol,
dibutylphosphate and Bis (2-hydroxypropyl) aminoethanol with Relative Standard
Deviation (RSD) 8,10 % and 12,40 µg/mL
for Bis (3-methylbutyl) ethylphosphonate and 3,46 % and 14,19 µg/mL for Bis
(2-chloroethyl) methylamine and 2,22 % and 11,28 µg/mL for Pinacolyl
methylphosphonate and 2,70 % and 11,47 µg/mL for Triethanolamine. Relative Standard Deviation is a homogeneity
value with requirements below 20 % and stability is a degradation result which
value is less than 30 %.
