摘要
Improvements to the electrical sensing zone instrument are described that allow the good accuracy of this type of instrument to be applied to the measurement of the size of particles of carbon black. The improvements include a concentrated aqueous electrolyte containing KI or NaI, a surfactant soluble in the electrolyte capable of dispersing particles of carbon black, and an anode electrode that is made of silver at the surface touching the electrolyte. The silver anode electrode prevents the degradation of the electrolyte by light and electrolysis.
