This Study presents the effect of different parameters that effect the production of biodiesel from used sunflower oil and the optimum conditions using potassium hydroxide as a catalyst. Each biodiesel production (transesterification) run was repeatedthree times. The optimization parameters such as oil to methanol ratio (1:03 to 1:10), potassium hydroxide concentration (0.25 to 2.0 wt %), time duration (15 to 120 min), and temperature ranging from 35 to 70oC were determined. The optimum parameters were found to be 1 wt % of potassium hydroxide, 1:07 oil to methanol ratio, 600C temperature,90 minutes of the reaction time and highest yield of biodiesel obtained was 95 %.

Radiometric techniques have acquired immense importance among all the analytical analysis techniques. They have the edge over other analytical techniques due to the advantages of being adequately accurate, rapid and cost effective with minimum need on sample preparation. Among the various radiometric techniques, Gamma ray spectrometry is one of the most widely applied techniques for identification and quantitative estimation of the radio elements in a variety of matrices. The wide range of applications of gamma ray spectrometry in the field of Radiation monitoring in nuclear facilities, National Security, Geochemical investigation, Health physics, Nuclear medicine, Material research and mineral exploration have made the technique globally popular. The underlying principle is that the energy of gamma photons emitted from radio isotopes is characteristic of individual isotopes. This requires appropriate radiation detector, pulse processing, sorting of pulses with amplitude, display of pulse distribution and interpretation, all included in a single set-up called as gamma ray spectrometer. The technique began with the use of single channel analyzers for sorting pulses and has evolved with the advancement in electronics and detector technology. Today portable gamma ray spectrometers which are very handy to carry for field use with powerful software to directly display the spectrum and also to analyze radio isotopes are quite common. The technique was applied for estimation of Uranium, Thorium and Potassium concentration in the soil and rock samples collected from the area around Mody University, Lakshmangarh.
