Electrode care

摘要

FAILING to ensure pH electrodes are properly maintained can have costly consequences.In mining, these electrodes are often used in processes such as heap leaching and flotation. They are also used to monitor the acidity of wastewater.Getting the acidity level wrong in the process side can lead to poor mineral recovery or the overuse of chemicals. On the wastewater side it can mean an expensive environmental issue.Endress+Hauser managing director John Immelman said properly maintaining pH electrodes gave more than just accurate measurements. It also made for a longer interval between cleaning cycles and extended productivity during a longer lifecycle.Users often believe a sluggish or non-responsive pH electrode means a failed probe. In most cases this probe can be "revived" by applying the correct chemical cleaning procedure.
