✦ Synopsis

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 flowing over the coated crystal for 5 min. Iron(II1) and cadmium interfered.
