Partial Purification of Viruses with an Anion Exchange Resin.

open access: yesExperimental Biology and Medicine, 1950
A variety of techniques have been developed for the purification of viruses. Methods which have been applied to poliomyelitis viruses include: adsorption to, and elution from alumina gel1 or aluminum hydroxide2; half saturation with ammonium sulfate3; filtration4; procedures involving ether extraction, protein precipitation and centrifugation or ...

Thermodynamics of ion exchange equilibrium for some uni-univalent and divalent reaction systems using strongly basic anion exchange resin Indion FF-IP

open access: yesBulletin of the Chemical Society of Ethiopia, 2008
The study on thermodynamics of ion exchange equilibrium for uni-univalent Cl-/I-, Cl-/Br-, and uni-divalent Cl-/SO42-, Cl-/C2O42- reaction systems was carried out using ion exchange resin Indion FF-IP.

Phosphate desorption from soil in anion-exchange resin extraction

open access: yesAgricultural and Food Science, 1978
An attempt was made to clarify the mechanisms of phosphate desorption using the anion exchange resin method for extraction of phosphorus from soil. It was shown that there is a linear dependence between the amount of phosphorus desorbed and the square ...

Chemical Pre-treatment Methods for Measurement of Ge Isotopic Ratio on Sphalerite in Lead-Zinc Deposits

open access: yesYankuang ceshi, 2014
Up to the present, main research of Ge isotopes has been carried out on organic, magmatic and meteoritic samples. Pb-Zn deposits are one of the most important reservoirs of Ge; however, there are few studies on Ge isotopes for these samples.
