Abstract

 IN THIS STUDY, WE EVALUATE THE ABSORPTION AND RELEASE OF PARAQUAT FORM CLINOPTILOLITE WITH CATION EXCHANGE RESIN OF PROPYL CARBOXYLIC ACID (PCA). RECOVERY PARAMETER, LIMIT OF DETECTION (LOD), LIMIT OF QUANTIFICATION (LOQ) AND WITHIN RUN ERROR (WRE) FOR PARAQUAT EXTRACTION FORM BLOOD WITH CLINOPTILOLITE WERE 81.7±3.4, 0.58 MGR/ML, 1.93 MGR/ML AND 7.1% RESPECTIVELY. ALSO THESE PARAMETERS FOR EXTRACTION OF PARAQUAT FROM BLOOD WITH PCA METHOD WERE 83.6±3.2, 0.49 MGR/ML, 1.63 MGR/ML AND 6.3%. THE RESULTS SHOWN THAT CLINOPTILOLITE CAN EFFECTIVELY USE AS AN ABSORBENT MATERIAL WITH A CATION EXCHANGE CAPACITY IN PARAQUAT EXTRACTION FORM BLOOD. CLINOPTILOLITE PORE SIZE WAS 5×7 AO (0.5×0.7NM) AND CATION EXCHANGE CAPACITY IN CLINOPTILOLITE AND PCA ARE 1.4-1.6 MEQ/GR AND 10 MEQ/GR RESPECTIVELY. ACCORDING TO THE CATION EXCHANGE CAPACITY OF CLINOPTILOLITE AND PCA IT IS ANTICIPATED THAT EACH GR OF THESE EXTRACT 1.4-1.6 MEQ/GR (=130-149 MG) AND 10 MEQ/GR (=931 MG) PARAQUAT RESPECTIVELY. CLINOPTILOLITE BET WAS MEASURED WITH NANO SORD DEVICE AND PARTICLE SIZE WERE MEASURED WITH PARTICLE SIZE ANALYZER (MASTER SIZER). POTENCIAL ZETA WAS MEASURED WITH ZETASIZER IN -27.9MV. SCANNING ELECTRON MICROSCOPE (SEM) FOR CLINOPTILOLITE WERE DONE BY FIELD-EMISSION SCANNING ELECTRON MICROSCOPE. PARTICLE SIZE ANALYZER RESULTS SUPPORT THE 11-40MM FOR POWDER.
