SEPARATION OF 235U, 238U AND THORIUM FROM MIXED RARE EARTH USING ION EXCHANGE RESIN

Nuclear Forensics / /

Authors: Kalaya Changkrueng, Saowaluck Thong-in and Harinate Mungpayaban Publication Type: The 42nd Congress on Science and Technology of Thailand Year: 2017 Abstract: Uranium isotope and thorium were separated in nitric acid form by using ion exchange column-resin. This experiment was tested in batch. Feed was prepared from uranium, thorium and rare earth elements (REE) in 80 ppb concentrations. […]

Solid phase extraction of uranium and thorium from various multi-element standard solution and geological sample

Nuclear Forensics, Uncategorized / /

Authors: Kalaya Changkrueng*, Saowaluck Thong-in, Harinate Mungpayaban Publication Type: The 2018 Pure and Applied Chemistry International Conference (PACCON 2018) Year: 2018 Abstract: Matrix effect is one of major problem of Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) technique. It will make inaccurate results. In some case the ratio of uranium isotope is quite sensitive necessity such as 235U/238U ratio. Solid phase

Determination of uranium isotopes in various kinds of water for nuclear regulation support using Inductively Coupled Plasma Mass Spectrometry

Nuclear Forensics, Publication / /

Authors: Ladapa Srijittawa, Saowaluck Thong-in , Harinate Mungpayaban Publication Type: The 2019 Pure and Applied Chemistry International Conference (PACCON 2019) Year: 2019 Abstract:  The analysis of 235U and 238U isotopes in three water types was studied using inductively coupled plasma mass spectrometry (ICP-MS). The waters from drinking water, radioactive waste, and surface water were collected and stabilized using concentrated HNO3
