- Abstract
In this study, Zn5(OH)8Cl2·H2O/PAM composite particles (CPs) were synthesized by precipitation reaction and emulsion polymerization in microreactors formed by nano water droplets when the hydrophilic-hydrophilic equilibrium (HLB) value was 5.76. The experimental results showed that Zn5(OH)8Cl2·H2O/PAM CPs were close to the spherical shape with an average diameter of about 736 nm. The CPs contained Zn-O bonds and were covered by PAM. The modified electrode by Zn5(OH)8Cl2·H2O/PAM had good cyclic voltammetry characteristics at scan rate of 100 mVs-1 and cyclic potential of +0.8-0.0V, and can detect 0.00001M iodide. In the range of 50-400 mVs-1, the peak current had a linear relationship with the square root of the scan rate and the electrochemical reaction of iodide onZn5(OH)8Cl2·H2O/PAM/GCE belonged to diffusion control kinetics.
