Penurunan Kadar Torium dan Radioaktivitas dalam Limbah Cair Proses Pengolahan Monasit PLUTHO Menggunakan Koagulan FeSO4
The separation of radioactive and rare earth mineral carried out in PLUTHO produces waste that still contains thorium and uranium. The resulting waste requires further processing to be environmentally friendly. The purpose of study is to reduce thorium content and radioactivity in liquid waste of PL...

The separation of radioactive and rare earth mineral carried out in PLUTHO produces waste that still contains thorium and uranium. The resulting waste requires further processing to be environmentally friendly. The purpose of study is to reduce thorium content and radioactivity in liquid waste of PLUTHO monazite treatment process using ferro sulphate coagulant. PLUTHO Pilot Plant is one of facility that built to dissociate uranium, thorium and light rare earth from mineral of monazite. Variations of treatments applied in the research are coagulant dosage and pH. Thorium content is measured by Spectrophotometer UV-Vis method, whereas radioactivity is measured by radiation counting meter Ludlum Model 1000 Scaler.
