Impact of environmental conditions on the sorption behavior of Pb(II) onto attapulgite

25-Nov-2012 | Yaling Chi, Yuantao Chen, Xia Liu, Zhijun Guo, Jiang Xiao, Jiangbo Xu, Wenhua Zhao, Journal of Radioanalytical and Nuclear Chemistry, 2012

This paper examined the application of attapulgite as an adsorbent for the removal of Pb(II) from heavy metal-contaminated water under various conditions. The sorption results indicated that the sorption of Pb(II) on attapulgite was strongly dependent on ionic strength at pH 10.0 was mainly ...

Study of radon, thoron and toxic elements in some textile dyes

25-Nov-2012 | H. A. Abel-Ghany, Journal of Radioanalytical and Nuclear Chemistry, 2012

Elemental analysis of textile dyes may provide valuable information concerning the content and concentrations of element, especially the toxic ones. Such information monitors the safety of handling and using these dyes in textile industry. In addition to the safety of wearing of clothes stained ...

An analytical algorithm for designing radon monitoring network to predict the location and magnitude of earthquakes

25-Nov-2012 | S. Mehdi Hashemi, Ali Negarestani, Mojtaba Namvaran, S. M. Musavi Nasab, Journal of Radioanalytical and Nuclear Chemistry, 2012

Continuous radon monitoring in soil and groundwater is one of the useful methods in earthquake prediction process. There are many published studies on geochemical precursors to seismic activity, both reporting the detection of validated precursory phenomena. The research on geochemical precursory ...

Adsorption of ytterbium onto Saccharomyces cerevisiae fungal cells: A pH-dependent contribution of phosphoryl functional group

25-Nov-2012 | MingYu Jiang, Toshihiko Ohnuki, Shinya Yamasaki, Kazuya Tanaka, Satoshi Utsunomiya, Journal of Radioanalytical and Nuclear Chemistry, 2012

The adsorption of ytterbium on the cells of yeast Saccharomyces cerevisiae has been studied by batch type experiment by changing solution pH. The Yb adsorption species on the yeast cell wall of the S. cerevisiae was determined by extended X-ray absorption fine structure spectroscopy combined with ...

Development of a method for the estimation of low amount of plutonium in 200 L waste drums in presence of high amount of β γ activity due to 137Cs and 60Co

19-Nov-2012 | Sarbjit Singh, Veena Sagar, Amol Mhatre, Journal of Radioanalytical and Nuclear Chemistry, 2012

The waste drum monitoring system based on HPGe detector was used to study its performance for the estimation of low amounts of plutonium in presence of high activity of 137Cs and 60Co. The counting was carried out by keeping amount of plutonium constant at 100 mg level and varying the count rate ...

Effect of grain size on the 85Sr2+ sorption and desorption in columns of crushed granite and infill materials from granitic water under dynamic conditions

19-Nov-2012 | Š. Palágyi, K. Štamberg, V. Havlová, H. Vodičková, Journal of Radioanalytical and Nuclear Chemistry, 2012

The sorption of 85Sr2+ in the form of 10−6 M Sr(NO3)2 in synthetic granitic water (SGW), and its desorption using the same radiotracer-free solution, were investigated under dynamic conditions in columns loaded with crushed granitic materials. The goal of study was to evaluate the influence of ...

Plutonium disproportionation: maxima in the fractions of two oxidation states

19-Nov-2012 | G. L. Silver, Journal of Radioanalytical and Nuclear Chemistry, 2012

The equilibrium fractions of soluble tri- and hexavalent Pu depend on the pH and the Pu oxidation number. Both fractions can exhibit maxima as the pH changes at constant N. A fraction at maximum can be used to estimate the equilibrium constant of the first hydrolysis reaction of tetravalent Pu. A ...

Remediation of soil/concrete contaminated with uranium and radium by biological method

19-Nov-2012 | Gye-Nam Kim, Seung-Su Kim, Hye-Min Park, Won-Suk Kim, Uk-Ryang Park, Jei-Kwon Moon, Journal of Radioanalytical and Nuclear Chemistry, 2012

Biological method was studied for remediation of soil/concrete contaminated with uranium and radium. Optimum experiment conditions for mixing ratios of penatron and soil, and the pH of soil was obtained through several bioremediations with soil contaminated with uranium and radium. It was found ...

Synergistic extraction of sodium into nitrobenzene by using hydrogen dicarbollylcobaltate and dodecaethylene glycol

19-Nov-2012 | E. Makrlík, P. Vaňura, P. Selucký, Journal of Radioanalytical and Nuclear Chemistry, 2012

Solvent extraction of microamounts of sodium by a nitrobenzene solution of hydrogen dicarbollylcobaltate (H+B−) in the presence of dodecaethylene glycol (DDEG, L) has been investigated. The equilibrium data have been explained assuming that the species HL+, H2L2+, NaL+ and NaHL2+ (L = DDEG) are ...
