Acacia nilotica (Thorn mimosa) is used locally for various medicinal purposes by traditionalists and herbalists in northeastern Nigeria. Plants products have been used since ancient times in the management of various conditions. The bark of A. nilotica has been reported to be used traditionally to manage diabetes, dysentery, leprosy, ulcers, cancers, tumor of the eye, ear and ...

in this study, a sensitive method of dispersive liquid phase microextraction based on ion-pair combined with the flame atomic absorption spectrometry was proposed for the determination of trace ni(ii) using aliquat 336-chloride as ion pair agent. several factors which have effect on  the microextraction efficiency of ni(ii), such as ph, extraction and dispersive solvent type and their volume, c...

a number of researches have been performed in the field of elemental analysis of fruitsfrom different areas of iran and there is a vast unstudied area in this field. in this study, seven mineral elements such as na, k, ca, mg, fe, zn and cu in the tree soil, citrus limunum juice of gorgan and iranshahr gardens and citrus limetta juice of gorgan and bandarabas gardens were determined by flame ph...

extraction of trace amounts of toxic heavy metals from complicated environmental matrixes is a  challenging task. the aim of this investigation is the comparison of the extraction efficiencies and other related experimental variables ( chemicals, effect of ph, potential interfering ions) on the determination of inorganic lead ( ) which is present in waste water of dye industries. compared techn...

the application of sulfur nanoparticles as an efficient adsorbent for the solid-phase extraction and determination of the trace amounts of pb and pd ions was investigated in environmental samples using flame atomic absorption spectrometry. effects of various parameters such as ph, flow rate of sample and eluent, type and concentration of eluent, sample volume, amount of adsorbent and interferin...

a simple, highly sensitive, accurate and selective method for determination of trace amounts of co(ii) in water samples is presented. isocyanate treated graphite oxides (igos) solid phase extraction adsorbent was synthesized by covalently isocyanate onto the surfaces of graphite oxides. the stability of a chemically (igos) especially in concentrated hydrochloric acid which was then used as a re...

the aim of this study was to determine and compare the concentration of copper (cu) in liver and muscle of two fish species squalius cephalus and capoeta capoeta gracilis. the fish were caught in four sampling sites along tajan river, mazandaran province, northern iran. the concentration of cu was determined using flame atomic absorption spectrometry. there were significant differences (p

The atomic absorption of aluminum with air-acetylene flame was interfered by the formation of involatile compounds in the flame. Amines promoted the atomization of aluminum in the flame. Aluminum could be determined by atomic absorption spectrometry with an air-acetylene flame. The absorption of aluminum increased and then attained a constant value as the concentration of amines increased. The ...
