质量标准 USAGE:
Product is autoclavable in sodium form. It has a maximum operating temperature of 75°C and is not soluble
in water.
Binding is a function of pH. Absorption is very low below pH 2 and increases sharply from pH 2 to 4. It
reaches a maximum above pH 4. Optimum binding for many divalent cations is at pH 6.5 or higher.1 Its
selectivity for divalent over monovalent ions is approximately 5000 to 1, and it has a very strong attraction
for transition metals, even in highly concentrated salt solutions. Actual selectivity values for any particular
system depend on the pH, ionic strength, and presence of other complex-forming species. Metals can be
removed using either the batch or column technique, although the column technique is more efficient. With
50-100 mesh, rapid flow rates are obtained and large volumes of solution can be processed in very little
time.
Resin can be regenerated by washing in the following sequence: 2 bed volumes of 1 N HCl, 5 bed
volumes water, 2 bed volumes of 1 N NaOH, 5 bed volumes water.
储存条件 常温密封避光保存,Stored in cool, dry and airproof.
