Abstract
This paper investigates the possibility of radium removal from brines using zeolites. Radium concentration in collected from hard coal mine water was as follows: 226Ra 3.3 ± 0.2 Bq/L, 228Ra 5.5 ± 0.5 Bq/L. Ten types of zeolites were selected for treatment: clinoptilolite, NaP1, NaX, 3A, 5A, 13X, Y, ZSM-5, SAPO-11, and SAPO-34. Sequential batch purification tests were performed. High efficiencies of radium removal from mine brine achieved with NaP1 and NaX, synthesized from fly ahes, are promising for the further application of obtained zeolitic materials, especially for water treatment. Furthermore, the use of zeolites derived from waste fly ash is an ecological and sustainable solution for environmental protection and remediation.
期刊介绍：
Water Resources and Industry moves research to innovation by focusing on the role industry plays in the exploitation, management and treatment of water resources. Different industries use radically different water resources in their production processes, while they produce, treat and dispose a wide variety of wastewater qualities. Depending on the geographical location of the facilities, the impact on the local resources will vary, pre-empting the applicability of one single approach. The aims and scope of the journal include: -Industrial water footprint assessment - an evaluation of tools and methodologies -What constitutes good corporate governance and policy and how to evaluate water-related risk -What constitutes good stakeholder collaboration and engagement -New technologies enabling companies to better manage water resources -Integration of water and energy and of water treatment and production processes in industry
