General description

Bis(ethylenediamine)copper(II) hydroxide solution is a stable complex formed by copper (Cu) ions with ethylenediamine. It is a transition metal solution that can be used as a catalyst for electrochemical reduction process.[1][2]

Application

Bis(ethylenediamine)copper(II) hydroxide has been used to evaluate cation exchange capacity (CEC) of clays by copper absorption.[3]
Copper(II) ethylenediamine complex may be used to evaluate the cation exchange capacity (CEC) of clay materials.[1] It may also be used to modify polyoxoniobate, which is a class of polyoxometalates (POMs) that finds potential application in photocatalytic H2 production.[4]

The beta-elimination of phosphoserine residues by dilute alkali is catalysed by the presence of group II metal ions. The use of 0.1 M-Ba (OH)2 catalysed the rate of beta-elimination of phosphoserine by more than two orders of magnitude compared with

This study investigated the durability, especially the nonwaterdegradable qualities, of experimental light-cured composite resin containing barium-borosilicate glass filler. For this purpose, Bis-GMA, a typical component of base monomer in conventional composite resin, was replaced by Bis-GMA-F which is water-repellent. After

Desflurane, enflurane and isoflurane can be degraded to carbon monoxide (CO) by carbon dioxide absorbents, whereas sevoflurane and halothane form negligible amounts of CO. Carbon monoxide formation is greater with drier absorbent, and with barium hydroxide, than with soda lime.
