摘要/Abstract

摘要： 研究了一种用漆酚铁树脂进行化学修饰的固体传感器的制备方法,并初步探讨了其提高金属离子测定灵敏度的机理。在HOAc+NaOAc和KNO₃混合介质中,该传感器测定铜离子的线性范围为4×10^-9mol/L至2.5×10^-7mol/L之间,富集20min后铜离子的检出限为8×10^-11mol/L。用于实际水样的测定,平均回收率可达99.10%,结果满意。

Abstract: Solid sensor modified by urushiol Fe resin was prepared for the determination of trace copper in water.Mechanism of increasing sensitivity has been studied.In 0.1 mol/L KNO₃ and HOAc NaOAc solution, peak current is linearly correlated with concentration over the range from 4×10^-9 mol/L to 2.5×10^-7 mol/L.Detection limit(signal to noise=3) is 8×10^-11 mol/L after 20 min accumulation.Using the electrode, Cu²⁺ in water samples were detected, and average recovery is 99.10%.

Key words: urushiol-Fe resin, solid sensor, chemical modification
