in order to determine the copper status and correlation between the ceruloplasmin and copper of serum and among the copper of serum, liver and kidney of slaughtered goats in shahrekord, blood, liver and kidney samples (10 gr) from 100 goats were gathered. the amounts of ceruloplasmin and copper of serum, liver and kidney were measured by sunderman - nomoto and shimadzu atomic absorption method,...
all analytical methods are generally based on the measurement of a parameter or parameters which are somehow related to the concentration of the species.an ideal analytical method is one in which the concentration of a species can be measured to a high degree precision and accuracy and with a high sensitivity. unfortunately finding such a method is very difficult or sometimes even impossible.in...
a simple, sensitive and selective method for solvent extraction and spectrophotemetric determination of lanthanum (ii) europium (iii), and cerium (iii) is described , the rare earth metals are extracted into chloroform solution of n-phenylbenzohydroxamic acid (pbha) at ph 9-10 various parameters are studied to optimize the extraction conditions. the molar absorptivity is found to increase from ...
The purpose of this study was to monitor the concentrations of mercury in the edible muscle, gill, liver, and skin of common carp (Cyprinus carpio) and silver carp (Hypophthalmichthys molitrix), in the Sanandaj Gheshlagh Reservoir, Iran. Mercury concentrations were assayed using Shimadzu AA 6600 atomic absorption spectrophotometer, and the results were given as µg/g wet weight. The level of mer...
Drinking water quality with respect to fluoride, iron, and nitrate content has been carried out in Kamrup district of Assam, India. Forty six different sampling stations were selected for the study. Iron was analyzed by using an atomic absorption spectrometer, Perkin Elmer AA 200, while fluoride was measured by the SPADNS method at 570nm and Nitrate content was measured by the phenol-disulphoni...
introduction: calcium critical limit in pistachio plants is about 1.3 percent of plant dried material; magnesium critical limit in pistachio leaves is about 0.6 percent of plant dried material. to measure calcium and magnesium there are several methods in which three methods of titration and atomic absorption that are more common and used to libraries more in addition to icp modern method are u...
Background and purpose: High concentrations of heavy metals have always been a major cause of contamination in aquatic ecosystem. Sturgeons are important sources of food and income throughout the world. In this study, concentrations of Cadmium, Vanadium, Nickel and Zinc (Cd, Ni, V and Zn) were examined in edible and inedible tissues of stellate sturgeon (Acipenser stellatus) and beluga (Huso hu...
