Aluminosilicate zeolites are strong cation exchangers, but the effectiveness at binding and removing quaternary ammonium compounds from a saline solution depends on pore size and framework type. Though it is not tested internally, most common zeolites have small pore windows that exclude bulky organic cations like many quaternary ammonium compounds (QACs) with long alkyl chains. Furthermore, in saline solutions, competition with abundant Na+ and Ca2+ greatly reduces the ion-exchange selectivity for QACs, diminishing removal efficiency.

General description
飽和した分子ふるいは、再生によって元の能力を取り戻します。再生の原則として、きわめて低い平衡容量に相当するように着剤周囲状態が変化します。一般に、吸着の平衡容量と再生の差が大きいほど、再生は迅速で完全となります。
分子ふるいは4通りの方法のいずれかで再生できます。
1.加熱再活性化ーシリカの最大再生温度は300℃です。
2.減圧再活性化
3.通常の温度および圧力で適切な流体をゲルベッドに通します。
4.流体中の高濃度の分子をベッドに通して吸着剤を置換します。
1.他の分子ではなく一定の1つの分子を選択する吸着
は、孔径およびメッシュサイズに依存します。
2.特定の化合物を吸着するシリカゲルの動的能力は内部表面積で決まります。表面積が大きいほど、動的能力が大きくなります。
3.吸着の速度と分離の正確さは、主として粒子サイズとカラム充填に依存します。粒子サイズが小さいと、分離の正確さが最適化されます。
4.液体は、その溶解度が最も低い溶媒から最も容易に吸着されます。適切な溶媒は適切な脱離剤となります。
5.極性が高い液体は容易に吸着されます。ヒドロキシ基を持つか酸素を含む化合物は、強く吸着されます。
6.同等の化合物の場合、分子量が高いほど選択性が高くなります。
7.同等の分子量の炭化水素は、二重結合の数が多いほど吸着性が高くなります。

Is it possible to encapsulate in it?
1 回答-
Zeolite is reportedly often utilized to encapsulate metals for use as catalysts. The particle size is expected to be <20 μm. Suitability would have to be determined by the researcher.

How can I determine the shelf life / expiration / retest date of this product?
1 回答-
If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.
