Abstract

Rhodamine B is a synthetic red dye which is commonly used as textile dyes and banned its use in food and beverages. The red dye is harmful to health and it can cause poisoning symptoms if it is swallowed, and it can damage the liver when it is taken long term. Although it has been banned because of its toxicity, but there is abuse of rhodamine B as a food coloring, such as in tomato sauce product. The purpose of this study is to validate the high performance liquid chromatography (HPLC) for analysis of rhodamine B in a tomato sauce. The analytical method used is HPLC with reverse phase system. The analytical method has met the requirements of method validation according to the International Conference of Harmonization with the detection and quantitation limits, 1 ppm and 3 ppm respectively. Based on the results of the qualitative analysis of rhodamine B in tomato sauce samples, one of the three samples of tomato sauce that is not listed in NA-DFC (The National Agency of Drug and Food Control) showed positive result, it was shown with the same retention time between samples and standards (5.5 minutes). Average level of rhodamine B in the sample was 25 μg/g of tomato sauce.

Abstract

CHROMATOGRAPHIC BEHAVIOUR OF CADMIUM-(II) IN HYDROUS CERIC OXIDE COLUMN. The potential of hydrous ceric oxide (HCO) in the immobilization of cadmium ions enables the compound to be used as an adsorbent for recovering 112Cd target in the production of medical radioisotope 111ln. Since the enriched-112Cd is very expensive, the dynamic sorption of 112Cd in HCO column needs to be evaluated. In the presented work, the HCO was synthesized through the reaction of ceric Sulphate and ammoniac solution. The reaction product was then heated and dried at 1000C to give HCO. A series of Cd(II) standard solutions was loaded onto HCO columns followed by fractional elution and determination of Cd(II)-content in each eluate fraction. The quantitative determination of Cd(II) content was performed by UV-spectrophotometry at 301 nm with a standard regression curve expressed as A = O.OOO1C - 0.0002. The chromatographic behaviour of Cd(II) in HCO column was characterized by dynamic sorption capacity, elution profile, recovery yield and total volume of the eluent. It appears that the dynamic sorption of Cd(II) increases if the HCO was treated with ammoniac solution instead of with 0.1 M HCL solution. By using NH4OH solutions (5 %, 10 % and 20 %) as eluents, it is shown that the concentration of NH4OH does not significantly affect the Cd(II)-elution profile. The recovery yield was obtained in the range of 94 to 100 %, while most the eluted Cd(II) was collected in the first and second- 2 mL fractions. PERILAKU KROMATOGRAFI KADMIUM-(II) DALAM KOLOM RESIN SERIUM OKSIDA. Potensi resin anorganik serium oksida (HCO) untuk mengikat ion kadmium mendorong kemungkinan pemanfaatan HCO dalam proses pemungutan ulang bahan sasaran 112Cd diperkaya yang digunakan dalam proses produksi radioisotop medis 111ln. Karena mahalnya bahan sasaran 112Cd tersebut, maka fenomena penyerapan dinamik 112Cd pada kolom resin HCO dipelajari dengan menggunakan Cd alam. Di dalam percobaan ini HCO disintesis melalui reaksi antara serium sulfat dengan larutan amonia. Produk reaksi dipanaskan dan dikeringkan pada suhu 100°C untuk mengubahnya menjadi HCO. Larutan standard Cd(II) dengan variasi konsentrasi dimasukkan ke dalam kolom HCO dan kemudian dilakukan elusi berfraksi diikuti dengan pemeriksaan kandungan Cd(II) dalam masing-masing fraksi eluat. Penentuan kuantitatif Cd(II) dilakukan dengan metoda spektrofotometri UV pada panjang gelombang 301 nm dengan persamaan regresi standar yang dinyatakan sebagai A = O,OOO1C - 0,0002. Sifat kromatografi Cd(II) dalam kolom HCO dipelajari melalui pengamatan terhadap 4 aspek yaitu kapasitas penyerapan dinamik, profil elusi, efisiensi elusi dan volume total eluen yang diperlukan. Didapatkan bahwa penyerapan dinamik Cd(II) pada kolom HCO yang diaktivasi dengan larutan HCL 0,1 M lebih rendah dibandingkan pada kolom HCO yang diaktivasi dengan larutan NH4OH (5 %, 10 % dan 20 %). Hasil percobaan menunjukkan bahwa penggunaan eluen NH4OH dengan konsentrasi 5 %, 10 % dan 20 % tidak memberikan perbedaan profil elusi Cd(II) yang signifikan. Dengan elusi berfraksi sebanyak 2 mL per fraksi eluat, didapatkan akumulasi Cd(II) terelusi pada 2 fraksi eluat pertama dengan efisiensi elusi antara 94 - 100 %.
