Abstract

An increasing demand of platinum group elements (PGE) especially platinum, palladium and rhodium in various industries has increased its concentration in the environment. Determination of PGE was measured in selected open and close sites using inductively coupled plasma – optical emission spectrometry (ICP-OES) and inductively coupled plasma – mass spectrometry (ICP-MS). Results showed that Pt concentration in road dusts of open sampling area are in the range of not detected (ND) to 200.0ng/g, while the concentration of Rh is in the range of 8.02ng/g to 97.32ng/g. Pt and Rh in close sampling area, Genting Sempah Tunnel are in the range of not detected (ND) to 105.7 ± 61.1ng/g and 8.4 ± 1.3ng.g to 59.0 ±5.5ng/g respectively. The ratio of Pt to Rh in road dusts samples ranges from 1.2: 1 to 7: 1, while the ratio in catalytic converter samples is 7: 1. There is no Pd detected in any of the samples taken. The correlation between Pt, Rh and trafficrelated elements with the traffic density of the sampling sites were discussed.


Permintaan terhadap unsur kumpulan platinum (PGE) yang semakin meningkat terutama bagi Pt, Pd dan Rh dalam pelbagai industri telah menyebabkan peningkatan kepekatannya di dalam persekitaran. Penentuan kandungan unsur PGE telah dilakukan di beberapa lokasi tertutup dan terbuka menggunakan teknik ICP-OES dan ICP-MS. Keputusan kajian menunjukkan kandungan Pt di dalam sampel debu jalan kawasan terbuka di dalam julat not detected (ND) hingga 200.0ng/g manakala kepekatan unsur Rh berada di antara 8.02ng/g hingga 97.32ng/g. kandungan masing-masing Pt dan Rh, di dalam sampel debu jalan di kawasan tertutup berada di dalam julat not detected (ND) hingga 105.7 ± 61.1ng/g dan 8.4 ± 1.3ng/g hingga 59.0 ± 5.5ng/g. Nisbah kandungan Pt kepada Rh di dalam sampel debu jalan berada di dalam julat 1.2: 1 dan 7:1, manakala nisbah di dalam sampel penukar bermangkin adalah 7: 1. Kandungan Pd tidak dapat dikesan di dalam kesemua sampel. Perkaitan antara kandungan Pt, Rh dan beberapa unsur lain dengan ketumpatan lalulintas di kawasan persampelan turut dibincangkan.
