the effect of acetate ion introduced to aqueous solutions was investigated for the extraction/separation of ni and co from a dilute sulfate media. the separation of co and ni was improved by introducing acetate to aqueous media. by the use of the slope analysis method,the stoichiometric coefficient of the extractant was found to be 4 for cobalt and 3.5 or 4 for nickel depending on the acetate c...

the present study evaluated the effect of packaging (air, vacuum) with or without addition of sodium acetate (2% w/v) on shelf-life extension of rainbow trout (oncorhynchus mykiss) under refrigeration, for a period of 18 days. four different treatments were tested: cap: control air pack; saap: sodium acetate treated aerobic packaging; vp: vacuum packaging in the absence of sodium acetate; and s...

preparation of tretinoin-containing microspheres with the aim of reducing undesirable skin reactions towards trans retinoic acid (tra) and thus, improving patient compliance is of particular interest. these microspheres have to be smaller than 30 m m to avoid causing gritty feel when applying on the skin, and slow the release of drug to minimize its skin side effects. following preliminary eval...
