Cyanide acclimation in willow (Salix babylonica L.), a prospect for the phytoremediation of cyanide
Phytoremediation counts as a major method for future which essentially needs resistance to contaminating agents. We pretreated the plants (Salix babylonica, as a model plant in phytoremediation of polluted waters) by sodium cyanide (0, 3 and 5 mg CN- L-1) to induce resistance with regard to acclimation and then examined their resistance to higher concentrations of cyanide. Accordingly, some of ...

متن کاملRemoval of iron-cyanide complexes using micellar-enhanced ultrafiltration
Micellar-enhanced ultrafiltration (MEUF)-based separation of iron-cyanide complexes, ferriccyanide and ferrocyanide, was investigated in order to assess the potential of MEUF for the removal of ferriccyanide and ferrocyanide with a cationic surfactant, cetylpyridinium chloride (CPC). The removals of ferriccyanide and ferrocyanide were >99% and 99%, respectively, with the molar ratio of CPC to f...
متن کاملMetabolism of hydrogen cyanide by higher plants.
A survey has been made of the occurrence and distribution of three enzymes which metabolize cyanide in a variety of higher plants including both cyanogenic and non-cyanogenic species. The enzymes investigated were beta-cyanoalanine synthase, rhodanese and formamide hydrolyase. beta-Cyanoalanine synthase was found to be present in every higher plant tested whereas rhodanese was found to occur fa...
متن کاملDestruction of cyanide and thiocyanate by ferrate [Iron(VI)]
A cyanide-laden effluent of the gold mining industry must be treated before it can be released to the aquatic environment. Current treatment methods such as natural degradation, sulfur based, hydrogen peroxide, ozonation, and alkaline chlorination are not adequate for meeting newer treatment standards. A new chemical oxidant that utilizes iron in the +6 oxidation state, ferrate [Fe(VI)] was stu...
