Poly( 2vinylpyridine) or poly(4-vinylpyridine) coated on a piezoelectric quartz crystal adsorbed copper, thus decreasing the oscillation frequency. The bound copper could be removed by EDTA solution. Poly( 4-vinylpyridine) is recommended to determine copper (5-35 MM) in a maleate buffer at pH 6.6 fl
A piezoelectric quartz crystal (PQC) is used for the quantification of carbon dioxide in still white wine. The methodology is discussed in terms of calibration stability and accuracy as a direct consequence of coating amount and absolute quantity of carbon dioxide in the samples. The method is compa
