in this study an easy, green, efficient and simple approach is reported for the synthesis of some benzothiazole-, benzimidazole- and benzoxazole-2-thiolderivatives. the proposed approach employs the reaction of corresponding aromatic amine with potassium isopropyl xanthate (z11) in the presence of copper sulfate (cuso4) as a catalyst under conventional heating and ultrasonic irradiation. the ad...

Copper sulfate or ‘blue vitriol’ is commonly used as a herbicide and fungicide. It is cheap and easily available, and can also be easily prepared in the laboratory. We report a fatal case of suicidal poisoning by copper sulfate by a pregnant adult female. Although medical treatment was instituted, the fatality ensued. Histopathological examination revealed hepatosplenomegaly and evidence of sep...

this experiment was conducted to investigate the effects of different levels of oxidized fat (yellow grease) and copper sulfate on performance, carcass traits, blood metabolites and immune cells of broilers. this study was carried out as a 3 × 2 factorial experiment with 3 levels of oxidized fat (0, 2 and 4%) and 2 levels of copper sulfate (0 and 300 mg/kg) in 6 treatments, 3 replicates and 12 ...

effects of ambient copper was investigated on serum stress markers, sodium and enzyme levels in common carp ( cyprinus carpio l.) over a 14-d exposure period. fish were exposed to 0, 25 and 100 μg l -1 copper (as copper sulfate) and blood was sampled at 0, 3, 7 and 14 d after exposure. serum profile was significantly affected by copper concentration, sampling time and their interaction. increas...

Male commercial broiler strain chickens were fed either a control diet (based on corn and soybean meal) or the control diet supplemented with cupric sulfate pentahydrate or cupric citrate in seven experiments (six in floor pens, one in wire-floored batteries). In Experiment 1, feeding 125 or 250 mg/kg copper increased growth (4.9%) and decreased feed conversion ratios (3.4%), total plasma chole...

In this study we investigated histopathological changes of mice ovarian tissues following long-term administration of copper sulfate and induction of chronic copper poisoning. The study comprised of three different groups of twenty one mice as follows: The first group (Group 100) which treated by gavage with copper sulfate at a dose of 100 mg kg-1 for 5 weeks. The second group (Group 200), whic...

Mung bean plants (Wilczek) accumulate increasingly greater amounts of buffer-extractable copper in both their shoots and roots when grown in liquid medium containing greater than 2 micrograms per milliliter copper (31.4 micromolar) as cupric sulfate. This increase in soluble copper is accompanied by an increase in the relative amount of low molecular weight (7,000 to 20,000) macromolecular-boun...

Background: Copper sulfate ingestion is a relatively popular method for committing suicide in Indian subcontinent. It causes a high mortality rate, and so a growing concern has been raised to identify the severe alarming signs suggestive of poor prognosis and to improve treatment approaches. Case report: A 22-year-old unmarried man working as a painter was found unconscious at his friend reside...

Background. Skin infections occur commonly and often present therapeutic challenges to practitioners due to the growing concerns regarding multidrug-resistant bacterial, viral, and fungal strains. The antimicrobial properties of zinc sulfate and copper sulfate are well known and have been investigated for many years. However, the synergistic activity between these two metal ions as antimicrobia...

For securing noble metal resources, recovery of metals from urban mines is a key technology. Recently, ammonium thiosulfate solution has attracted attention as safe and low-cost for gold leaching. We previously reported process using electroless displacement deposition onto silicon powder. In this study, we tried to use powder recover an leaching solution. experimentation, added simulated conta...
