Adsorption of 2-picoline and 3-Amino-2-picoline onto Kaolin and Organo-modified Kaolin
The adsorption of 2-picoline (PC) and 3-Amino-2-picoline (APC) onto kaolin and organomodified kaolin was investigated. Tetraethylamoniumiodide (TEAI) was used as modification reagent. The sorbent was characterized by FTIR, XRD, SEM and BET methods. The influence of various parameters like contact time, PH, adsorbent dose and initial concentration of PC and APC was studied. The adsorption kineti...
متن کاملDetermination of pyridine, 2-picoline, 4-picoline and quinoline from mainstream cigarette smoke by solid-phase extraction liquid chromatography/electrospray ionization tandem mass spectrometry.
The present paper describes the development and validation of a new reversed-phase liquid chromatography-electrospray ionization tandem mass spectrometric method (RP-HPLC-ESI-MS/MS) for simultaneous determination of pyridine, 2-picoline, 4-picoline and quinoline from mainstream cigarette smoke. Liquid-liquid extraction followed by solid-phase extraction was applied to extract the target analyte...
متن کاملPlatinum Complexes with Picoline-functionalized Benzimidazolin-2-ylidene Ligands
The dicarbene platinum complexes of the type [Pt(L)2]Br2 [5]Br2 – [8]Br2 (L = N-alkyl-N′picolylbenzimidazolin-2-ylidene) have been prepared by two different methods. The in situ deprotonation of picoline-functionalized benzimidazolium salts 1 – 4 with platinum acetylacetonate gave the platinum complexes [5]Br2 – [8]Br2 in good yields. Complex [8]Br2 has also been obtained by a ligand transfer r...

متن کاملdevelopment of different optical methods for determination of glucose using cadmium telluride quantum dots and silver nanoparticles
a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...
