Purification of siderophores of Alcaligenes faecalis on Amberlite XAD

Bioresource Technology, 2006
Studies on siderophore production using Alcaligenes faecalis BCCM ID 2374 revealed hydroxamate and catecholate type of siderophores at 347 microg mL-1. These fractions were purified on Amberlite XAD-4 column, which resulted in the separation of two bands having absorption maxima at 264 and 224 nm.

Lithium adsorption by acid and sodium amberlite

Journal of Colloid and Interface Science, 2003
In this paper we used a previously reported model for examining the adsorption of nonelectrolytes in solution by solid adsorbents to study the adsorption of lithium(I) cations by acid and sodium amberlites, which is an ion-exchange process. Based on the results, both are equilibrium processes and obey a kinetic law with a unity partial order in the Li+

Anion exchange in Amberlite IRA-400 and Amberlite IRA-410 ion exchange resins

Journal of Chemical & Engineering Data, 1992
Equilibrium for the binary exchange of anions on Amberlite IRA-400 and Amberlite IRA-410 was measured. Standard methods were used to determine operating characteristics of both resins. Equilibrium data were obtained by the batch method. The fitting of binary ion exchange isotherm equations is an important aspect of data analysis.

Hemoperfusion with Amberlite Resin in the Treatment of Self‐Poisoning

Acta Medica Scandinavica, 1980
ABSTRACT. Ten patients with various intoxications were treated with resin hemoperfusion. Three of four patients with grade IV coma due to tricyclic antidepressant (TCA) poisoning could be extubated during or on termination of hemoperfusion. Clearance values of 135–185 and 190–200 ml/min were obtained for amitriptyline and nortriptyline, respectively ...

An excellent fluoride sorption behavior of modified amberlite resin

Journal of Hazardous Materials, 2010
The article describes a convenient method for the modification of Amberlite XAD-4 resin by introducing thio-urea binding sites onto the aromatic rings. The modified (ATU) resin has been employed for the quantitative sorption of fluoride ions in batch as well as column experiments. The parameters (i.e.

Comparison of Chitin and Amberlite IRA‐938 for α‐Galactosidase Immobilization

Artificial Cells, Blood Substitutes, and Biotechnology, 2003
Watermelon alpha-galactosidase (EC 3.2.1.22) was immobilized on a natural (chitin) and a synthetic anion-exchange (Amberlite IRA-938) support by covalent coupling methods. The procedure entails the activation of supports with 1,1'-carbonyldiimidazole (CDI), followed by immobilization of the enzyme on to these supports without and with a spacer arm ...
