A blend with better properties could be obtained by adding phenolic resin 2402/tin bichloride (8/0. 5) curative and a certain level of dioctylphthalate plasticizer and HAF reinforcing agent.
In the paper, a PVC membrane picric acid anion selective electrode is developed using Bromhexadecyl pyridine picrate ion pair as the active component and dioctylphthalate as the plasticizer.
