Kinetics of Ion-Isotopic Exchange Reactions using Nuclear Grade Resins Purolite NRW-4000 and Purolite NRW-60
Abstract: AbstractThe paper deals with an application of nondestructive radio isotopic tracer technique in performance evaluation of two nuclear grade anion exchange resins Purolite NRW-4000 and Purolite NRW-6000. The technique was used to study the kinetics of bromide and iodide ion-isotopic exchange reactions taking place between the external ionic solution and the resin surface for which 131I and 82Br were used as tracer isotopes. It was observe that at a constant …

Nondestructive Technique in Study of Purolite NRW-5010 and Duolite A-638 Anion Exchange Resins
Abstract: The present paper is one of the interesting applications of radioactive isotopes in nondestructive technique for performance evaluation of anion exchange resins Purolite NRW-5010 and Duolite A-638. The radioactive isotopes 131I and 82Br were used to trace the kinetics of ion-isotopic exchange reactions taking place between the resin surface and external ionic solution. It was observed that for bromide ion-isotopic exchange reaction at 35.0°C, when the concentration of bromide ions …

Thermodynamic Concept to Evaluate the Performance of Organic Base Ion Exchange Resins Purolite NRW-5050 and Indion-870 Using Short-Lived Radioisotopes
Abstract: The present paper deals with application of short-lived radiotracer isotopes to understand the performance of Purolite NRW-5050 (nuclear grade) and Indion-870 (non-nuclear grade) anion exchange resins. The performance evaluation was done based on thermodynamics of iodide and bromide ion-isotopic exchange reactions. It was observed that for Purolite NRW-5050 resins during the bromide ion-isotopic exchange reaction, the enthalpy and energy of activation values calculated were 3287.8 and 5869.3 J.mol-1 respectively, which …

Performance Evaluation Studies of Purolite NRW-5010 and Indion AGR Anion Exchange Resins by Radioactive Tracer Technique
Abstract: AbstractThe characterization of organic base anion exchange resins Purolite NRW-5010 and Indion AGR was made by application of short lived radio tracer isotopes 131I and 82Br. The characterization of the two resins was based on their performance during iodide and bromide ion-isotopic reaction taking place between the resin surface and the external labeled ionic solution. The exchange reactions were carried out by using the ionic solution in the concentration range …

Intelligent Water Distribution Management using IoT
Abstract: Water plays a vital role in agriculture, making its efficient management essential for sustainable crop production. However, undetected leaks in irrigation systems can result in significant water loss, irregular watering of fields, soil degradation, and reduced crop yield. Conventional methods like manual inspection are not only labor-intensive but also ineffective in identifying leaks promptly – emphasizing the need for a smarter and automated approach to water monitoring. To address this …
