Transport abilities of new synthesised membrane materials incorporating tetrapyrazolic tripods.

The article discusses a study on the synthesis of solid membrane films that use the photopolymerisation containing the tetrapyrazole active monomers spread on a polyacrylonitrile support. The resulting materials were used to extract and facilitate the transport of Cadmim, Plumbum and Mercury. The new formulation prepared contains methacrylic monomer, styrene and photostart and the dense membranes were obtained through esterification of acyclic hydroxy-tetrapyrazoles with meth-acryloyl chloride.
