Contents of available P extracted by Mehlich-1 (A) and anion exchange resin
(AER) (B) in a Red Nitosol after application of complexes and cultivated with wheat in greenhouse
The extractants used in the study were 0.5 M Acetic acid (Korndorfer et al., 1995), Sodium acetate buffer (Morgan, 1941), Ammonium acetate buffer (McIntosh, 1969), Sodium bicarbonate (Olsen et al., 1954), Acidified ammonium fluoride (Bray and Kurtz, 1945) and Anion Exchange Resin
A sample of the strong base anion exchange resin
#3 was subjected to ten decolorization cycles by weighing out 10g (dry weight) of resin into 200mL of crude filtered vancomycin broth and shaking the contents for two hours on an orbital shaker.
The inorganic P extracted with anion exchange resin
([Pi.sub.RTA]) and NaHC[O.sub.3] ([Pi.sub.bic]) and the organic P extracted with NaHC[O.sub.3] ([Po.sub.bic]) are the first extractants used in the chemical fractionation of P (Hedley et al., 1982).
It was showed that the adsorption of Ni(II) with D301R anion exchange resin
was mainly not ion-exchange adsorption mechanism but the surface complexation through the infrared spectrum analysis.
It is comprised of a blend of an anion exchange resin
having a particle size of 0.5 to 50 microns, the anion exchange resin
is prepared by a process selected from the group consisting of suspension polymerization, phenol formulated condensation and condensation polymerization of at least one polyamine and epichlorohydrin; with a water-insoluble addition copolymer.
We also tested the effectiveness of an anion exchange resin
membrane to concentrate orthophosphate and remove colloids and other interferences from the analyte solution in order to minimise these problems.
Another anomaly involves an anion exchange resin
, phosphates, and a temperature reversal of the ion-exchange.
Strongly acidic cation-exchange resin, strongly basic anion exchange resin
, and mixed bed columns of weakly acidic cation exchange resin and weakly basic anion exchange resin
were used with a stevidoside (purity 80-87%) showing recovery of about 79% .
One was filled with a strong base acrylic macroporous anion exchange resin
and granular activated carbon (GAC).
