6Determining Natural Radiation Level in River Water of Upper Euphrates(Karasu)Basin’s Part Located in Erzincan Province Borders显示文摘Within the scope of this study,it is aimed to contribute to the efforts for forming a database including the natural radiation levels throughout the country and developing a foundation for radiation safety.Karasu portion of the Euphrates valley within the provincial border of Erzincan was chosen for the investigation and natural radiation levels were detected by analyzing the samples taken in terms of radioactivity,natural environment’s radiation streams.Throughout the region of Karasu,29 different samples from the water and 17 from the soil were taken and their total alpha,beta activities were detected.To take samples from the water and then they were measured by low background counter(Berthold brand LB770 10-channel counter).Total alpha and beta analyses were made according to the standard methods.Average values of alpha and beta concentrations of samples were measured as 0.0421 Bq/L and 1.806 Bq/L,respectively.For the soil samples HPGe gamma spectrometer system was used and radioisotope activity concentrations were found within the intervals of 2.7-27.8 Bq/kg for 226Ra;3.2-39.4 Bq/kg for 232Th;98-714 Bq/kg for 40K;<0.4-57.8 Bq/kg for 137Cs,respectively.Different radioisotopes were detected in some of the samples taken from streaming beds joining river water.Pasa Yalcin Mehmed Kavaz Muhammet Yildirim Erol Kam 2018Journal of Physical Science and Application2018,8,2:0
7Unravel the potential of zinc oxide nanoparticle-carbonized sawdust matrix for removal of lead(Ⅱ) ions from aqueous solution显示文摘Zinc oxide nanoparticles(ZnOnp) are molecular nanoparticles synthesized by a chemical precipitation method from zinc nitrate tetrahydrate and sodium hydroxide.Carbonized sawdust(CSD) was prepared from sawdust obtained from a local wood mill.The matrix of both provides a better material as an adsorbent.The present study applied the functionality of ZnOnp,CSD,and ZnOnp-CSD matrix as adsorbent materials for the removal of Pb(Ⅱ) ions from aqueous solution.The method of batch process was employed to investigate the potential of the adsorbents.The influence of pH,contact time,initial concentration of adsorbate,the dosage of adsorbents,and the temperature of adsorbate-adsorbent mixture on the adsorption capacity were revealed.The adsorption isotherm studies indicate that both Freundlich and Langmuir isotherms were suitable to express the experimental data obtained with theoretical maximum adsorption capacities(q_(m)) of 70.42,87.72,and 92.59 mg·g^(-1) for the adsorption of Pb(Ⅱ) ions onto ZnOnp,CSD,and ZnOnp-CSD matrix,respectively.The separation factors(R_(L)) calculated showed that the use of the adsorbents for the removal of Pb(Ⅱ) ions is a feasible process with R_(L) <1.The thermodynamic parameters obtained revealed that the processes are endothermic,feasible,and spontaneous in nature at 25-50℃.Evaluation of the kinetic model elected that the processes agreed better with pseudo-second order where the values of rate constant(k_2) obtained for the adsorption of Pb(Ⅱ) ions onto ZnOnp,CSD,and ZnOnp-CSD matrix are 0.00149,0.00188,and 0.00315 g·mg^(-1)·min^(-1),respectively.The reusability potential examined for four cycles indicated that the adsorbents have better potential and economic value of reuse and the ZnOnp-CSD matrix indicates improved adsorbent material to remove Pb(Ⅱ) ions from aqueous solution.Racheal Aigbe Doga Kavaz 2021Chinese Journal of Chemical Engineering2021,34,1:0
