Electrocatalytic Properties of a Novel β-PbO2/Halloysite ...

To improve the efficiency of electrochemical degradation of ,wastewater,, lead dioxide was synthesized by a hydrothermal method with low cost, simple operation, and high conversion rate. β-PbO2/HNT composites were prepared by a hydrothermal method with Halloysite nanotubes (HNTs) and β-PbO2. The PbO2/HNT/ITO electrode was prepared by modifying the β-PbO2/HNT composite on an indium tin …

scope: These test methods2 cover the determination of ,acidity, or alkalinity of all types of water. Three test methods are given as follows: In all of these test methods the hydrogen or hydroxyl ions present in water by virtue of the dissociation or hydrolysis of its solutes, or both, are neutralized by titration with standard alkali (,acidity,) or acid (alkalinity).
