Determination of Ni Impurities Using Cadmium-Selective Electrode
Taking into account the use of Nickel brasses in industry a great number of methods for the determination of Ni have been reported. More, theoretical predictions of free Cd increasing with decreasing salinity have been confirmed using cadmium selective electrodes. The method under proposal, for the determination of nickel ions in brass alloys consists of the following steps: Cu masking with sod...
متن کاملUultra-trace determination of cadmium (II) in aqueous environmental samples by a new ion selective electrode based on nefazodone and 1-butyl-3-methylimidazolium hexafluorophosphate ionic liquid
Background and Objective: Cadmium is a potential environmental contaminant that causes adverse effects on the environment and the health of living organisms. Therefore, designing a simple and economic technique for its determination is very important. In this respect, a potentiometric sensor based on nefazodone as the ionophore and [BMIM]PF6 as the ionic additive were developed for the determin...
متن کاملUncoupling of oxidative phosphorylation by cadmium ion.
Mitochondria from rat liver were isolated in 0.25 M sucrose according to Schneider (5) and suspended in 1 ml. of 0.25 M sucrose per gm. of fresh liver. Rabbit liver mitochondria, used only for the experiments in Table I, were prepared by grinding the tissue in 0.25 M sucrose in a Waring blendor at reduced speed (6) and were suspended in 1 ml. of sucrose solution per 2 gm. of liver. The reaction...
متن کاملSelective Membrane Electrode for Bromide Ion Based on Aza Pyrilium Ion Derivative as a new Ionophore.
A highly selective electrode for Bromide ion based on aza pyrilium derivative as an excellentionophore is described.The sensor exhibits a good linear response with a slope of ( 60±1 ) mV per decadeover the concentration range of ( 1×10-3 – 9×10-6 M ) , and a detection limit of ( 3×10-6 M ) of Bromideions .The electrode response is independent of pH in the range of(4.0 –9.5).Selectivity coeffici...
متن کاملSelective determination of cadmium(II) from divalent metal ions in environmental samples by capillary electrophoresis using in-capillary complexation with a lacunary Keggin-type [PW11O39]7- complex.
A novel capillary electrophoretic (CE) method, based on in-capillary complexation with [PW(11)O(39)](7-), was developed for the determination of cadmium(II) in natural water samples. When a sample solution is injected into a capillary containing 0.20 mM [PW(11)O(39)](7-) and 0.10 M malonate buffer (pH 3.0), the ternary Keggin-type complex, [P(Cd(II)W(11))O(39)](5-), which possesses high molar a...
