This paper focuses on the quantitative determination of the loss of the components from plastic membranes of ion-selective electrodes (ISEs) during contact with aqueous bathing solutions. The leaching processes, which affect the ISE responses, are rarely characterized by independent methods.

Talanta, 80(3), 1311-1317 (2009-12-17)
Two different derivatizing reagents were tested for the development of a fast and sensitive method for the determination of selenites (Se(IV)) in human urine. The reagents were sodium tetraethylborate (NaBEt(4)) and tetraphenylborate (NaBPh(4)), respectively, and the procedure is based on

A biopolymer ε-poly-L-lysine (εPL) exists as a fully protonated form (εPLH(n+)) in solutions at pH < 4. Around pH 3.5, at which the tetraphenylborate (TPB(-)) anion is not decomposed immediately, the εPLH(n+) cation associates with the TPB(-) anion to form

Bioprocess and biosystems engineering, 34(5), 639-645 (2011-01-22)
In the pH 6.6 Na2HPO4-NaH2PO4 buffer solutions and in the presence of urease catalyst, urea can be decomposed to form NH4+. The NH4+ reacted with sodium tetraphenyl boron (NaTPB) to form the association particles that exhibited a resonance scattering (RS)

The construction and electrochemical response characteristics of two new polyvinyl chloride (PVC) membrane sensors for the determination of sibutramine hydrochloride were described. The sensors are based on the ion association complexes of sibutramine with sodium tetraphenylborate (NaTPB) or phosphotungstic acid
