Pelindian Natrium Zirkonat Menggunakan Asam Klorida Secara Catu

Abstract

ABSTRAKPenelitian tentang teknologi pengolahan zirkon terus dilakukan untuk mengikuti kebutuhan industri pasar. Pengolahan natrium zirkonat dengan pelindian menggunakan asam klorida sebagai pelarut telah dilakukan. Penelitian ini bertujuan mempelajari pengaruh ukuran butir, temperatur, dan kecepatan pengadukan terhadap zirkon terambil. Penelitian dilakukan dengan memasukkan pelarut (asam klorida 4 N) ke dalam reaktor, kemudian pelarut tersebut dipanaskan sambil diaduk. Umpan dengan ukuran butir tertentu dimasukkan ke dalam reaktor. Kondisi temperatur dan kecepatan pengadukan dijaga tetap. Setelah kondisi operasi tercapai, proses dihentikan kemudian disaring. Hasil penelit ian dengan analisis XRF menunjukkan bahwa kondisi proses optimum dicapai pada ukuran butir 90 µm, temperatur 80

Identification of TENORM in Zirconium Oxychloride with Gamma Spectrometry

“…From Table 2 the result of activity concentration of U-238 is 13.43 Bq/kg with the calculation statistic has a standard deviation value (SD) = 0.4377 Bq/kg with a repetition of 4 times the enumeration. Correction derived from nuclear constants is the probability of U-238 derived from the child (Pb-214 and Bi-214) which is 32.645% [6], taken 5% assuming normal data distribution then the default uncertainty radionuclide U-238 is 0.008161% presented in Table 3. From the calculation results using radionuclide Eu-152 and SRM IAEA-315 detector efficiency of 4.182% with standard deviation (SD) = 0.1976% and the standard uncertainty of detector efficiency is = 0.0988%.…”

“…In the nuclear industry, this material when combined with other metals (Zircalloy) then this alloy will be able to be done as a fuel cladding of nuclear reactors and many become large corrosion-resistant materials [3]. In the nuclear industry, this material can be processed into zirconia or in advanced ceramic materials due to its high strength and very high melting point (2700°C) [6,7].…”
