STUDIES ON A NEW NITROFURAN DERIVATIVE AS A FOOD PRESERVATIVE-III

Selective 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...

an overview on the effects of sodium benzoate as a preservative in food products

context food spoilage has been a common problem throughout history, and much of the spoilage is caused the activity of microorganisms or enzymatic reactions during the storage of food. thus, using chemical substances could prevent or delay food spoilage and this has led to the great success of these compounds in the treatment of human diseases. sodium benzoate is one of the synthetic additives ...

Spectroscopic studies on the interaction of sodium benzoate, a food preservative, with calf thymus DNA.

The interaction between sodium benzoate (SB) and calf thymus DNA in simulated physiological buffer (pH 7.4) using acridine orange (AO) dye as a fluorescence probe, was investigated by UV-Vis absorption, fluorescence and circular dichroism (CD) spectroscopy along with DNA melting studies and viscosity measurements. An expanded UV-Vis spectral data matrix was resolved by multivariate curve resolu...

Lanthanum(III) Ion Selective Electrode Based on a New Ionophore

A PVC membrane electrode based on 1-[({[(butylsulfunyl)carbothioyl]disulfanyl} carbothioyl)sulfanyl]butane as a suitable ion carrier for determination of lanthanum(III) ion was prepared. This electrode revealedsuch a good selectivity toward La3+ ion over a wide variety of other metal ions. Some experimental parametersuch as membrane composition, nature, and amount of plasticizer, the amount of ...
