摘要

聚乙烯醇(PVA)是一种有益的聚合物,能够形成有助于广泛应用的水凝胶。基于 PVA 与硼砂交联的水凝胶能够与去污剂结合,已被用于去污受污染表面的 99Mo。在 PVA-硼砂配方中引入氢氧化铝,以提高凝胶去除表面 99Mo 的效率。以玻璃、不锈钢和木材等不同表面为例,对配方进行了研究。当水凝胶喷洒在不同的表面上时,它能迅速形成并很好地附着。此外,该水凝胶还能有效净化被 99Mo 污染的表面,玻璃、不锈钢和木材的去污因子(D.F)最大值分别为 43.5、31.3 和 19.6。

Experimental study for the decontamination of various surfaces from 99Mo using PVA/Borax/Al(OH)3 strippable hydrogel

Polyvinyl alcohol (PVA) is a beneficial polymer capable of forming hydrogels helpful in a wide range of applications. Hydrogels based on cross-linking of PVA with borax, and able to incorporate with a decontaminating agent have been used in the decontamination of 99Mo from contaminated surfaces. Aluminum hydroxide has been introduced in the formulations of PVA-borax, to increase the gel efficiency for 99Mo decontamination from surfaces. The formulations were investigated with glass, stainless steel, and wood as examples of different surfaces. When the hydrogel is sprayed on different surfaces, it forms rapidly and adheres well. Moreover, the hydrogel was shown to efficiently decontaminate surfaces contaminated with 99Mo by a maximum value of decontamination factor (D.F) for glass, stainless steel, and wood to be 43.5, 31.3, and 19.6 respectively.

期刊介绍: Applied Radiation and Isotopes provides a high quality medium for the publication of substantial, original and scientific and technological papers on the development and peaceful application of nuclear, radiation and radionuclide techniques in chemistry, physics, biochemistry, biology, medicine, security, engineering and in the earth, planetary and environmental sciences, all including dosimetry. Nuclear techniques are defined in the broadest sense and both experimental and theoretical papers are welcome. They include the development and use of α- and β-particles, X-rays and γ-rays, neutrons and other nuclear particles and radiations from all sources, including radionuclides, synchrotron sources, cyclotrons and reactors and from the natural environment. The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria. Papers dealing with radiation processing, i.e., where radiation is used to bring about a biological, chemical or physical change in a material, should be directed to our sister journal Radiation Physics and Chemistry.
