background: phenol is an organic pollutant found in industrial effluents that is very toxic to humans and the environment. this study used pomegranate peel ash as a natural absorbent to remove phenol from aqueous solutions. methods: in this study, pomegranate peel ash in different doses was used as a new adsorbent for the removal of phenol. the effects of contact time, ph, adsorbent dose and in...

We describe several transinterface electron-transfer processes occurring at the benzonitrile (PhCN)/water interface that produce excited states. When an electrode was moved very close to the interface or even through the interface to produce an electrode/thin layer organic phase/aqueous solution configuration, the electrogenerated radical species formed in the PhCN phase (C12-Ru(bpy)3, DPA+, or...

A unique heterophase ligand exchange induced etching process was used to transform gold nanoparticles into organic-soluble fluorescent gold clusters which were assigned to Au(8) by optical spectroscopy and MALDI-TOF mass spectrometry. Both the annihilation electrochemiluminescence of fluorescent Au(8) clusters in organic solution and the coreactant electrochemiluminescence of Au(8) cluster film...

An effective and simple process for the isolation of 106Ru from high-level liquid wastes was developed. Radioactive ruthenium was oxidized by H5IO6 in HNO3 solution and was extracted to CCl4 phase in the form of RuO4. In order to obtain ruthenium in the suitable form for production of brachytherapy sources, RuO4 in organic phase was reduced and re-extracted to aqueous phase. The efficiency of e...

Purely organic room temperature phosphorescence (RTP) materials have aroused increasing interests in recent years and been widely applied anti-counterfeiting, biological imaging, sensing, etc. Currently, these can be efficiently developed crystalline states amorphous polymer-doped systems. However, achieving RTP solution, especially water is still a formidable challenge. Recently, reports on aq...

A simple, rapid and efficient dispersive liquid–liquid microextraction by use of ionic liquid (IL-DLLME)method, followed by flame atomic absorption spectrometry (FAAS) was developed for the preconcentrationand determination of palladium in water samples. In this method, an appropriate mixture of acetone and octylmethyl imidazolium hexafluorophosphate was injected rapidly into the aqueous sample...

Silver nanoclusters composed of only a few metal atoms present appealing properties such as fluorescence. We have previously reported on aqueous solutions of this fluorophore using poly(methacrylic acid) as scaffold and their sensing properties. Here we report on the preparation of organic solutions of fluorescent silver nanoclusters by quantitative transfer from aqueous solution to an immiscib...

The ability of a solute (inorganic or organic) to distribute itself between an aqueous solution and an immiscible organic solvent has long been applied to separation and purification of solutes either by extraction into the organic phase, leaving undesirable substances in the aqueous phase; or by extraction of the undesirable substances into the organic phase, leaving the desirable solute in th...
