Quick Detection of DINP in Samples by Molecular Imprinted Sensor
摘要
Abstract
An electrochemical sensor based on molecularly imprinted sensor for quick detection of DINP was developed in this research.Firstly,imprinted polymer particles(MIPs)were prepared through thermal polymerization.Then,MIPs and agarose were mixed in proportion.The electrochemical sensor for DINP was fixed by the mixture on a glassy carbon elec-trode.The sensor can be combined with the template molecule DINP and its electrochemical signals are influenced by DINP concentration.Thus,it could be used to detect DINP levels in samples,and DINP concentration was quickly detected in wine samples without sample pretreatment.The linear equation in this study wasΔI=0.03c+3.07,the correlation coefficient is R2=0.998,the linear range was 5×10-8-1×10-6,mol/L,the sensitivity limit was 2.7×10-8,mol/L,and the recovery rate was 105.3%,-115.7%,.关键词
