We developed a simple, rapid, and accurate method to determine the quantity of sulfur in soda-lime silicate glass using inductively coupled plasma atomic emission spectroscopy (ICP-AES) and sulfur separation using an alumina column. This method requi

The concentrations of 9 polybrominated diphenyl ethers (PBDEs) and 28 polychlorinated biphenyls (PCBs), including the 7 indicator PCBs and 12 dioxin-like PCBs, were determined in indoor dusts from electronic repair workshops in southern Nigeria. The

O-(1′-[18F]fluoropropan-2′-yl)-l-tyrosine (1-[18F]FPT) was synthesized using the Ni(II)-(S)-[N-2-(N′-benzylprolyl)amino]benzophenone-S-tyrosine based precursor. The precursor was synthesized through a two-step process starting from RS-tyrosine,

This study provides data on distribution of phthalate esters (PAEs) in the water and sediments in the Ori stream, Iwo, Nigeria. The liquid-liquid extraction method was employed, followed by cleaned up in an alumina column using hexane. Chromatographi

[18F]FET was synthesized using O-(2′-tosyloxyethyl)-N-trityl-l-tyrosine-tert-butyl ester (TET) precursor. SPE purification of [18F]FET, after radio-synthesis, using neutral alumina column was satisfactory, with radiochemical and enantiomeric purity

In this work, molybdenum-99 loaded columns were challenged with Bacillus subtilis vegetative cells and Bacillus pumilus spores inside and outside the alumina column, and microbial recovery and radiation effect were assessed. Alumina was a barrier for

Alumina is usually used for 99Mo absorbers obtained from 235U fission product because the use of 235U is getting limited, and as an alternative 99Mo obtained from natural MoO3 irradiation was used. The problem is that 99Mo produced was not carrier-fr

Method of W separation from fission- 99 Mo solution was studied using alumina column and H2SO4/ HNO3 eluents. The distribution coefficients of WO4 2- and MoO4 2- ions and the column loading/eluting conditions were investigated to optimize the separat
