3-Aminopropyltriethoxysilane (1 ), 3-aminopropylsilatrane (2 ), acrylonitrile, methylacrylate and acrylamide were purchased from Sigma-Aldrich (Merck KGaA, Darmstadt, Germany). The objects of study were natural zeolite of the Kholinsky deposit (Russia), calcium heulandite, Ca[Al2Si7O18]⋅6H2O (Z ), commercial chromatography grade silica gel 60–120 Mesh (S ) and slides glass (G ) 1 cm × 1 cm.
The procedure earlier described was used to immobilize silanes on the zeolite (Z ) surface [38 (link)]. Syntheses of silane-functionalized silica gel (S ) and glass (G ) were described in [39 (link),40 (link)], respectively. Reagents of high or analytical purity were used for all sorption experiments. The 1 mg mL−1 Au(III), Rh(III) and Pd(II) standard stock solutions were prepared by dissolving pure HAuCl4·4H2O, RhCl3·3H2O and PdCl2 in dilute HCl, respectively [37 (link)].

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
