Abstract

Emulsion liquid membrane systems are double emulsion drops. Two immiscible phases are separated by a third phase which is immiscible with the other two phases. The liquid membrane systems were classified into two types: (1) carrier mediated mass transfer, (2) mass transfer without any reaction involved. Uranium extraction, molyb-denum extraction and solvent extraction were used as purposed elements for each type of the membrane systems in the derivation of their mathematical models. Mass transfer in emulsion liquid membrane (ELM) systems has been modeled by several differential and algebraic equations. The models take into account the following : mass transfer of the solute from the bulk external phase to the external phase-membrane interface; an equilibrium reaction between the solute and the carrier to form the solute-carrier complex at the interface; mass transfer by diffusion of the solute-carrier complex in the membrane phase to the membrane-internal phase interface; another equilibrium reac-tion of the solute-carrier complex to release the solute at the membrane-internal phase in-terface into the internal phase.Models with or without the consideration of film resistances were developed and compared. The models developed in this study can predict the extraction rate through e-mulsion liquid membranes theoretically. All parameters required in the models can be de-termined before an experimental extraction run. Experimental data from literature (urani-um extraction) and (molybdenum extraction and solvent extraction) were used to test the models. The agreements between the theoretical predictions and the experimental data were very good. The advantages of emulsion liquid membrane systems over traditional methods were discussed. The models developed in this research can be used directly for the design of emulsion liquid membrane systems. The results of this study represent a very significant step toward the practical applications of the emulsion liquid membrane technology.

Abstract

Electroplating process of uranyl nitrate and effluent process has been carried out in order to collect uranium contained therein using electrode Pt / Pt and Pt / SS at various currents and times. Material used for electrode were Pt (platinum) and SS (Stainlees Steel). Feed solution of 250 mL was entered into a beaker glass equipped with Pt anode - Pt cathode or Pt anode - SS cathode, then fogged direct current from DC power supply with specific current and time so that precipitation of uranium sticking to the cathode. After the processes completed, the cathode was removed and weighed to determine weight of precipitates, while the solution was analyzed to determine the uranium concentration decreasing after and before electroplating process. The experiments showed that a relatively good time to acquire uranium deposits at the cathode was 1 hour by current 7 ampere, uranyl nitrate as feed, and Pt (platinum) as cathode. In these conditions, uranium deposits attached to the cathode amounted to 74.96% of the original weight of uranium oxide in the feed or 206.5 mg weight. The use of Pt cathode for  uranyl nitrate, SS and Pt cathode for effluent process feed gave uranium specific weight at the cathode of 12.99 mg/cm2, 2.4 mg/cm2 and 5.37 mg/cm2respectively for current 7 ampere and electroplating time 1 hour.Keywords: Electroplating, uranyl nitrate, effluent process, Pt/Pt electrode, Pt/SS electrode

Abstract

ADSORPTION OF URANIUM SIMULATION WASTE USING BENTONITE TANIUM DIOXIDE. Bentonite is a clay material of high surface area that have galleries within its structure. Bentonite that is modified with TiO2 will have high adsorption capability. In this study, natural bentonite and bentonite:TiO2 were characterized with FTIR, XRD and BET instruments to determine functional group, basal spacing, and specific surface area. This study also investigates the adsorption of bentonite:TiO2 in various environmental factors, such as pH (pH 1, 3, 5, and 8), contact time (10, 20, 30, 40, 50, 60, 70, 90, and 120 min), and initial uranium concentration (20, 40, 60, 80 ppm), and their influences on adsorption capacity, and determine the kinetics equation and adsorption isotherm. Based on FTIR analysis, a decrease in the band of O-H bond from water molecule was observed, which indicates the presence of TiO2 in bentonite interlayer structure. The XRD characterization of bentonite:TiO2 does not show diffraction peak in 001 plane. This is due to delamination of bentonite interlayer structure. Delamination is caused by the presence of TiO2 in large quantities, thus damaging the bentonite interlayer structure into irregular sheets. Bentonite as sheets will cause the basal spacing to increase and it is anticipated that XRD will find it difficult in detecting the 001 plane at a low 2 theta angle. The surface area of bentonite:TiO2 has increased by 12.04 m2/g. The maximum adsorption capacity of U(VI) took place at pH 5.0 for 70 minutes contact time and uranium concentration of 60 ppm. In this study, the adsorption kinetic and adsorption isotherm are pseudo second-order kinetic and Langmuir isotherm. The kinetic constant and maximum adsorption capacity of bentonite:TiO2 are 0.075 g/mg.min and 5.848 mg/g respectively.Keywords: Bentonite, TiO2, Adsorption, Uranium

Abstract

Aktivitas pertambangan dapat berpotensi menimbulkan keberadaan Technologically Enhanced Naturally Occuring Radioactive Material (TENORM). Salah satu radionuklida yang terkandung dalam TENORM adalah stronsium pada air produksi sebagai radionuklida terlarut. Jika masuk dalam tubuh, stronsium bisa menyebabkan penyakit kanker tulang, tumor, dan leukimia. Pada penelitian ini stronsium dihilangkan dari larutan dengan teknik adsorpsi secara batch menggunakan zeolit terpilar titanium dioksida. Penelitian ini bertujuan untuk mempelajari kinetika adsorpsi stronsium oleh zeolit terpilar titanium dioksida menggunakan tiga model kinetika, yaitu pseudo orde satu, pseudo orde dua, dan model kinetika Langmuir-Hinshelwood. Berdasarkan studi kinetika yang telah dilakukan maka diperoleh kesimpulan bahwa adsorpsi stronsium oleh zeolit terpilar titanium dioksida mengikuti model kinetika pseudo orde dua dengan nilai k2 sebesar 0,6022 (g/mg.menit) dan qe secara teoritis sebesar 9,5785 mg adsorbat/g adsorben.
