All starting materials for the synthesis of cinnamaldehyde modified dendron (CMD) were obtained from Sigma-Aldrich. Vulcan carbon was a kind gift from Cabot Corporation. PVC was purchased from Aldrich. Tetramethyl silane was purchased from CIL. Potassium tetrakis(4-chlorophenyl) borate (KTCPB), sodium tetrakis [3,4-bis(trifluoromethyl) phenyl] borate (NaTFPB), and dioctyl sebacate (DOS) were purchased from TCI. 1-Nitro-2-(n-octyloxy) benzene (NPOE) was purchased from Alfa Aesar. An anion excluder, sodium tetraphenylborate (NaTPB), was obtained from Merck, and metal chlorides (Mn+= Na+, K+, Mg2+, Ca2+, Cu2+, Fe2+, Co2+, Zn2+, and Pb2+) from TCI was used without any further purification. Deionized water (18 MΩ) was used to make aqueous solutions.

Fabrication of Polymeric Ion-Selective Membranes

Check if the same lab product or an alternative is used in the 5 most similar protocols
In this experiment, for the fabrication of the membrane, tetrahydrofurane was used as the solvent, and polyvinyl chloride powder (high molecular weight, PVC) was used as the matrix; both were purchased from Flucka. Dioctylphthalate (DOP) and dibutylphthalate (DBP) were procured from Merck, while 2-Nitrophenyl octyl ether (oNPOE) and nitrobenzene (NB) were procured from Flucka, and benzyl acetate (BA) was purchased from Aldrich; all was utilized as sensor plasticizers. The following lipophilic anionic additives were also used: sodium tetraphenyl borate (NaTPB) purchased from Merck, while potassium tetrakis (4-chlorophenyl) borate (KTK), sodium tetrakis (4-fluorophenyl) borate (NaTFPB), and tetradodecylammonium tetrakis (4-chlorophenyl) borate (ETH 500) were purchased from the Flucka company. De-ionized water is used throughout the experiments.
A TiCl3 (Merck) Ethylenediaminetetraacetic acid disodium salt (EDTA) was used as a titrant (Sigma-Aldrich), while nitric acid (HNO3), hydrochloric acid (HCl), and sodium hydroxide (NaOH) (Merck) was used to adjust the pH of the solution. The cationics nitrate and chloride with the highest purity level were purchased from Merck, Fluka, Aldrich, BDH, and HmbG companies, and used after vacuum drying over P2O5.

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.
