a chelating resin of polystyrene divinylbenzene resin functionalized by 1-(2-pyridylazo) 2- naphtol (psdvb-pan) has been synthesized and its sorption properties have been investigated for preconcentration and determination of cadmium at μg/l level by flame atomic absorption spectrometry. the procedure is based on the sorption of cd(ii) ions on a minicolumn of synthesized chelating resin. the...

Heavy metals were determined in samples of fish tissues, soil, and water from nine randomly selected farms based on production facility (earthen pond) the Ekiti Central (EC), North (EN) South (ES) senatorial districts state. Fresh collected tissues dorsal area used for analysis. Soil using a soil auger, air-dried stored sterile well-labeled polythene bag. The bottles (2L) labeled. After digesti...

Abstract The proton-boron aneutronic fusion reaction has numerous potential applications varying from controlled nuclear reactor to broad-energy spectrum α-particle source, as well uses in medicine, where it can serve a source for radioisotope production, or directly proton boron capture therapy. However, and its by-products should be investigated extensively provide stable secondary ion source...

Tpx3Cam is a newly developed time-stamped camera. With the ability to record arrival time and position of each event simultaneously, it becomes powerful tool in atomic molecular research. As an inherent weakness, time-walk effect resulting deviation major obstacle improving experimental resolution reconstruction momentum along time-of-flight. We analytic expression describe correct effect, whic...

The concentration of selected trace metals (Fe, Cd, Cu, Pb, and Zn) in 30surface sediments were measured using Atomic Absorption Spectrometer to investigatethe spatial and seasonal variations of trace metals along Kanyakumari coast, India. Toassess the environmental risk of trace metals, enrichment factor, geo-accumulation index,pollution load index, and ecological risk index have been calculat...

A novel, simple, sensitive and effective method has been developed for preconcentration of Hg(II) on nano-Fe3O4-DOP-ED solid-phase extraction adsorbent. In this paper, Dioctyl phthalate (DOP) was used to encapsulate nano-Fe3O4 and produce a nano-Fe3O4-DOP sorbent based new sorbent was prepared. This was treated with ethylenediamine (ED) in another solvent-free procedure for the formation of a n...
