Flow-injection Post-chemiluminescence Determination of Furazolidone in Animal Feeds
The post-chemiluminescence (PCL) reaction was observed with the mixture solution after completion CL reaction of luminol-H2O2 in present of Furazolidone (FZD). A novel method for the determination of FZD was established by flow-injection PCL. The CL intensity responded linearly to the concentration of FZD in the range 1.0×10 −7 -1.0×10 −5 g mL -1 , with a linear correlation of 0.9949. The detec...
متن کاملGraphene oxide-modified electrodes for sensitive determination of diethylstilbestrol.
This paper reports an electrochemical sensor fabricated with graphene oxide (GO) modified on a chitosan-coated glassy carbon electrode (GO-CS/GCE) and its application for the detection of diethylstilbestrol (DES). It was observed that the effective electrochemical surface area of the GO modified electrode was nearly 10 times that of the bare GCE. This could be used to explain the results that t...
متن کاملInvestigation of Aflatoxins in Imported Animal Feeds in Iran
Background: Aflatoxins (AF’s) are secondary metabolites produced by certain species of fungi on grains and animal feeds. Because of serious impact of AF’s on health, they should be monitored closely in potentially hazardous foods and feeds. Method: In this study, AF’s in imported animal feeds including cereals, corn gluten and meals (pastes derived from the cotton, colza and sunflower seeds) f...
متن کاملPellet Quality in Animal Feeds
Pelleting costs money, and better pellets cost a little more. Payback comes in the form of convenience in handling the feed and more efficient use of the feed by the animal. Improved efficiency is due in part to heat processing which reduces pathogens and makes starches more digestible. A significant portion of the improvement is related to the physical form of the pellet. Durable pellets reduc...
متن کاملPart 558—new Animal Drugs for Use in Animal Feeds
(a) Acceptable daily intake (ADI). The ADI for total residues of virginiamycin is 250 micrograms per kilogram of body weight per day. (b) Tolerances—(1) Swine. Tolerances are established for residues of virginiamycin in uncooked edible tissues of 0.4 part per million (ppm) in kidney, skin, and fat, 0.3 ppm in liver, and 0.1 ppm in muscle. (2) Broiler chickens and cattle. A tolerance for residue...
