The method has the characteristics of high accuracy, high easiness in operation,convenience and quickness.

Description

technical field [0001] The present invention relates to a kind of analytical detection method, specifically a kind of nickel complex [NiL] (ClO 4 ) 2 The invention relates to a method for detecting syringic acid by a catalytic nonlinear oscillation system, which belongs to the field of quantitative analysis chemistry. Background technique [0002] Syringic acid, also known as 3,5-dimethoxy-4-hydroxybenzoic acid, has a structure as shown in formula (I). Syringic acid and its derivatives are important pharmaceutical intermediates, agricultural chemicals and photosensitizers, etc., and are in great demand in the international market. Syringic acid is a chemical monomer extracted from Dendrobium. Because it contains phenolic hydroxyl groups, it is more likely to undergo changes such as oxidation, polymerization, and synthesis, and has good antioxidant and free radical scavenging capabilities. Syringic acid also has a medicinal effect. The medicinal effect mainly includes ant...
