Tris(pentafluorphenyl)boran

Determination of the leaching of polymeric ion-selective membrane components by stripping voltammetry.

Beata Paczosa-Bator et al.

Talanta, 81(3), 1003-1009 (2010-03-20)

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.

Comparison of tetraethylborate and tetraphenylborate for selenite determination in human urine by gas chromatography mass spectrometry, after headspace solid phase microextraction.

D C Kapsimali et al.

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

Separation and purification of ε-poly-L-lysine from the culture broth based on precipitation with the tetraphenylborate anion.

Hajime Katano et al.

Analytical sciences : the international journal of the Japan Society for Analytical Chemistry, 28(12), 1153-1157 (2012-12-13)

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

A novel and sensitive resonance scattering assay for detection of urea in serum coupled urease catalytic reaction and NH4+ associated particle reaction.

Aihui Liang et al.

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)

Sibutramine selective electrodes for batch and flow injection determinations in pharmaceutical preparations.

S I M Zayed et al.

Analytical sciences : the international journal of the Japan Society for Analytical Chemistry, 26(1), 45-49 (2010-01-13)

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
