Sodium borohydride treatment systems for control of heavy metal discharge offer several advantages to the photographic industry. Chemical reduction with sodium borohydride is rapid and results in low residual metal content; in addition, the reduced metals can be recovered with minimum expense. Sodium borohydride reduction is now being used to recover high purity silver from spent fixers more co...

Reduction of oxi me fu nctionality to amine is an important synthetic transformation . As ox imes are stable derivatives of carbonyl compounds, subsequent reduction to amines is an attractive two-step procedure for reductive ami nation . Red uction of oximes to amines can be performed by hydride reducing agents or by catalytic hydrogenation.' Among hydride reducing agents, lithium aluminium hyd...

iron oxide (fe2o3) nanoparticles were synthesized by a simple approach using sodium borohydride (nabh4) and iron chloride hexahydrate (fecl3.6h2o). their physicochemical properties were characterized by high resolution transmission electron microscopy (hrtem), scanning electron microscopy (sem), x-ray diffraction (xrd) and electron dispersive spectroscopy (eds). xrd pattern showed that the iron...
