【摘要】 本文利用线扫极谱法研究了镉(Ⅱ)-邻菲啰啉(Phen)二元络合物与透明质酸(HA)的相互作用并建立了以Cd(Ⅱ)-Phen二元配合物为电化学探针测定HA的分析测试方法。在最佳实验条件下,Cd(Ⅱ)-Phen还原峰电流的降低值同HA的浓度在4.0~110.0mg/L范围内呈良好的线性关系,线性回归方程为Δip"(nA)=3.98 C(mg/L)+30.79(n=17,γ=0.993),检测限为3.23mg/L(3σ)。将本方法应用于模拟样品中HA的测定,结果令人满意。更多还原

【Abstract】 In this work,the interaction of Cd(Ⅱ)-Phen with HA was investigated by linear sweep polarographic method,accordingly a new approach for HA determination using Cd(Ⅱ)-Phen as an electrochemical probe was established.Under the optimal conditions,the reduction peak current of Cd(Ⅱ)-Phen decreases proportional to the HA concentration in the range of 4.0-110.0 mg/L,the linear regression equation was got as Δip"(nA)=3.98 C(mg/L)+30.79(n=17,γ=0.993) with the detection limit as 3.23 mg/L(3σ).The proposed method was further applied to determine the HA content in the synthetic samples with good results and good recovery.更多还原
