Abstract

The piezoelectric bulk acoustic wave sensor technology has such unique advantages as high sensitivity, wide response spectrum, easy digitalization, simple structure and low cost and others, which are widely used in many fields of analytical chemistry, biochemistry, environmental monitoring, life science and molecular biology. This article has conducted research for theories and applications of several new systems on the basis of the tandem piezoelectric response to solution electrical conductivity and dielectric constant and the response of single-component piezoelectric bulk acoustic wave sonic sensors to the viscosity and density, which has broadened the application range of the piezoelectric bulk acoustic wave sensor applications in the life sciences and environmental monitoring. The article applies tandem piezoelectric sensor technology (SPQC) to study the adsorption properties of natural polymer chitosan to metal ions, and the influence from ion concentration, adsorbent dosage and degree of deacetylation of chitosan to chitosan sequestration performance has been investigated in the article. In addition, the determination of degree of deacetylation has been conducted with the application of tandem piezoelectric sensor technology in the article, this test method can effectively eliminate the influence of residual acid or residual alkali adsorbed by chitosan, making measurement results become more accurate and reliable.
