The sample, after being purged by reversed extraction and purified byPVP - kieselguhr column, was enriched throughAmberliteXAD - 7 column. 样品经过乙酸乙酯反萃取及PVP - 硅藻土层析柱后, 再径XAD - 7柱浓缩. 互联网 The therapeutic effect of hemoperfusion with activated charcoal orAmberliteXAD - 7 ...
It is based on chemical sorption of cadmium(II) ions onto a minicolumn packed with Amberlite XAD-2 resin loaded with TAM reagent. After being preconcentrated, cadmium was eluted by 0.50 mol l−1 hydrochloric acid solution and straight determined on-line by flame atomic absorption spectrometry....
The commonly used or- ganic polymers, which are often found in a chromato- graphic column are: Tenax GC, based on 2,6-diphenyl- 370 Adsorption Kinetics and Breakthrough Behaviour of TBP on Amberlite XAD-4 Resin 371 ppentylene oxide(g);Propack Q, an ethylvinylbenzene- divinylbenzene ...
A small precolumn (40 2 mm i.d.) packed with Amberlite XAD7 facilitates the determination of ciprofloxacin in serum by permitting direct injection of a relatively small volume (100 L) of diluted serum. A 0.05 M phosphate buffer (pH 7.0) washes out the plasma components. AcetonitrileMethanol...

column-mode separationextractant-impregnated resinsquercetinA new chelating polymeric sorbent as an extractant-impregnated resin (EIR) has been developed using brilliant green (BG) and Amberlite XAD-7 resin. The BG-impregnated resin showed superior binding affinity for Cr(VI) in the presence of ...
Column data were used to scale up the process industrially. Bisphenol-A (BPA) was removed from water solution using washed (WX7) and impregnated (IX7) Amberlite XAD-7 resin with Aliquat-336 (A336). 0.5 g (IX7-0.5) and 1 g (IX7-1) of A336 per g of WX7 wer...
Cobalt was preconcentrated as N,N ′-bis(pyridine-2-yl-methyl)benzene-1,4-diamine (Co-BPMBDA) from sample solutions using a column containing Amberlite XAD-7 and was determined. In order to achieve the best performance for the method, effects of several parameters such as pH, concentrations...
A column chromatography was developed using a nonionic, polar adsorbent resin Amberlite XAD-7 for routine radiochemical separation of 67 Ga from Zn and Cu. 7M HCl was found to be the optimum concentration for adsorption of 67 Ga and elution of both Zn and Cu. Distilled water was used for ...
