Pewarna azo dan reaktif merupakan dua kelas pewarna organik digunakan secara
meluas dalam pelbagai aplikasi terutamanya industri pembuatan batik. Pewarna
Black 5 Reaktif (RB5) dikategorikan dalam pewarna azo vinylsulfonat disebabkan
kewujudan ikatan –N=N- yang bergabung dengan vinylsulfonat sebagai kumpulan
reaktif. Pembentukan amine aromatik yang bersifat karsinogen hasil daripada proses
penurunan kumpulan azo memberi risiko pengumpulan bio dalam rantai makanan
manakala pewarna reaktif mempunyai jangka hayat yang lama dalam persekitaran.
Pelbagai kaedah telah digunakan untuk penentuan pewarna seperti kromatografi dan
elektroforesis kapilari (CE) tetapi kaedah-kaedah tersebut kompleks dan mempunyai
kos peralatan yang tinggi, keperluan dan kepelbagaian yang tinggi terhadap bahan
kimia dan penyediaan sampel, penyelanggaraan serta pekerja mahir.
Azo and reactive dyes are two classes of organic dye mostly used in various
applications especially in batik industry. Reactive Black 5 (RB5) dye is categorized
in vinylsulphonate azo dye group due to the presence of –N=N- bonds combined
with vinylsulphone as the reactive group. The production of carcinogenic aromatic
amines, resulted from azo reduction has a significant risk of bioaccumulation in the
food chains whereas reactive dyes have a long half-life in environment. Various
methods have been used for dye measurements such as a chromatography and
capillary electrophoresis (CE) but they are well-known for their complex and high
cost instrumentation, high and multiple requirements on chemicals and sample
preparation, maintenance and skilled labour.
