Aqueous suspension of nano zirconia with methanol was irradiated with gamma (γ ) rays. Hydrogen (H2) generated in this process was studied as a function of pH and γ-dose. In the presence of 1 M methanol and at pH 3.0, low gamma dose irradiation showed optimum H2 generation. This is explained on the basis zeta potential and surface charge on zirconia particles. Positive surface charge at low pH could be the reason for enhanced H2 generation. Maximum H2 yield G(H2) of 3.7 was observed. This is 400 times more compared to nano pure water. The method can be utilized for building a medium-scale H2 generation plant.Keywords

The Bhabha Atomic Research Centre (BARC), Mumbai, over the last five decades has made pioneering contributions in the development and applications of radioisotopes and radiation technology for industry, medicine and agriculture leading to significant benefits to the society. This article briefly discusses various applications of radioisotopes and radiation technology in the industry presently being pursued at BARC. The main areas of application include radiotracers and sealed sources for industrial troubleshooting, radiography and tomography for NDT applications, and nucleonic gauges for quality control in industrial processes. The radiation processing technology, on the other hand, is an effective, economical and environmentally friendly alternative to conventional methods used for various industrial processing applications. Presently, 24 gamma irradiators and 18 electron-beam machines are commercially operating in India for various radiation processing applications.Full Text
