2012年2月5日 · Currently, the most widely used method for quantitative analysis of TCEP is indirect UV spectrophotometry. The sample containing TCEP is combined with a known molar excess of 5,5′-dithiobis (2-nitrobenzoic acid) (DTNB or Ellman's reagent).

2017年11月1日 · Removal efficiency and detoxification of TCEP using UV/TiO 2 are evaluated. Degradation of TCEP by UV/TiO 2 involves hydroxylation and dechlorination. Proteomics analysis is used to evaluated detoxification of TCEP. Preliminary incomplete degrading products can be utilized by Escherichia coli.

2020年12月1日 · UV/H 2 O 2 system is an effective method to degrade TCEP in aqueous solution. TCEP was transformed to several hydroxylated and dechlorinated products. The degradation products of high concentration TCEP were more toxic. Tri (2-chloroethyl) phosphate (TCEP) with the initial concentration of 5 mg/L was degraded by UV/H 2 O 2 oxidation process.

Properties: Odorless, air-stable, white crystalline solid. mp 176°. uv max: 192, 218 nm (e 150, 180 L mol-1 cm-1). Water soluble. pKa 7.66. When pH of dilute solutions is less than pKa, air oxidation occurs slowly. Use: Biochemical tool for selective reduction of disulfide bridges at low pH; reductant for redox assays.

2012年12月12日 · The photooxidation degradation of tri (2-chloroethyl) phosphate (TCEP) by combining UV with hydrogen peroxide as oxidant was primarily studied in the present study by evaluating various treatment parameters.

毒理学研究表明，TCEP 可破坏内分泌系 统，产生神经毒性、生殖毒性和发育毒性,对人类健康构成威胁．本研究来用紫外/过氧化氢 (UV/ H<SUB>2</SUB>O<SUB>2</SUB>）体系完成 TCEP 的去除反应，通过调控水体C1^- 浓度和反应水体，探究TCEP 的降解规律。

本研究将稳态自由基浓度模型与同位素分馏相结合，研究无机阴离子对紫外线/过硫酸盐 (UV/PS) 降解 TCEP 的影响。 在 UV/PS 系统中不存在阴离子的情况下，观察到的降解率为 (9.7 ± 0.1) × 10 -5 s -1，大约 93 % 归因于硫酸根（SO 4 -•) 基于自由基模型的氧化。

2022年11月19日 · TPHP的光降解路径主要是P—O—C键断裂、苯环结构的C—H键断裂和水解反应.利用UV-H 2 O 2 体系对成都市环境水体中OPEs进行降解实验, 发现对公园景观水体的水样进行降解反应60 min时, TPHP的去除率为66%.

2021年9月14日 · Experimental results showed that TCEP had a significant removal efficiency in UV/Fe (III) ( [TCEP] 0 = 10 ppm, [Fe 2 (SO 4) 3] 0 = 0.5 mM, near-100% degradation rate after 90 min). A free radical scavenging experiment and EPR detection indicated that the formation of ·OH by the Fe (III) under ultraviolet light played a major role.

2016年5月26日 · I have a problem when I used TCEP to reduce the disulfide bond in my polymer. After I put TCEP (together with hexylamine and triethylamine- I want to do simultaneous aminolysis and reduction)...
