Abstract
The purpose of the presented work entailed the development of a simple, high throughput sample preparation method for determination of a wide range of veterinary drugs at regulatory levels in milk, chicken meat and egg. pretreating the veterinary drugs include SPE pretreatment was combined with sample homogenization, acetonitrile and sodium sulphate salt extract and precipitate protein, n-hexane removal of fats, centrifugation and filtration. To proceed this goal, titania / octavinyl POSS (TiO2 / OVP) nanocomposite was prepared by sol – gel method and it was used to coat the surface of commercial cotton fabric. POSS supplies numerous organic and inorganic groups, facilitating the...
