Reduction of gold ions to gold particles by reusable soluble poly (tyramine) polymerized by horseradish peroxidase / Hidetaka Kawakita in Industrial & engineering chemistry research, Vol. 49 N° 22 (Novembre 2010)  

Public ISBD [article]  inIndustrial & engineering chemistry research > Vol. 49 N° 22 (Novembre 2010) . - pp. 11582-11586 Titre : Reduction of gold ions to gold particles by reusable soluble poly (tyramine) polymerized by horseradish peroxidase Type de document : texte imprimé Auteurs : Hidetaka Kawakita, Auteur ; Yuko Yoshimura, Auteur ; Keisuke Ohto, Auteur Année de publication : 2011 Article en page(s) : pp. 11582-11586 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Gold Ions Résumé : A novel recovery method is proposed for gold ions using poly(tyramine), which is reductive and has easily manipulated solubility. Tyramine, which has phenol and amino groups, was polymerized using horseradish peroxidase. When the HCl concentration in solution was increased, poly(tyramine) solubility decreased, probably due to chloride ion coordination with the poly(tyramine) amino group. Poly(tyramine) was highly soluble at pH DEWEY : 660 ISSN : 0888-5885 En ligne : http://pubs.acs.org/doi/abs/10.1021/ie100127g [article] Reduction of gold ions to gold particles by reusable soluble poly (tyramine) polymerized by horseradish peroxidase [texte imprimé] / Hidetaka Kawakita, Auteur ; Yuko Yoshimura, Auteur ; Keisuke Ohto, Auteur . - 2011 . - pp. 11582-11586.
