Problems solved by technology

However, it only focuses on traditional laboratory testing, and there are limitations in sample pretreatment steps such as complex, time-consuming, low throughput, and high cost
However, the rapid detection technology for drug residues in aquatic products is very scarce. The traditional detection methods in the current laboratory are difficult to achieve fast and efficient detection results, and are increasingly unsuitable for the characteristics of food production, distribution and sales.

Abstract

The invention discloses a sulfonamide test paper. The sulfonamide test paper is prepared by immersing a blank test paper in a mixed solution for 2-15 min, taking out and drying in an oven, wherein the mixed solution is prepared from, by mass, 3-50% of sodium sulfate, 1-30% of methanol, and 0.1-10% of derivatization reagent; the solvent is de-ionized water. The derivatization reagent is prepared by mixing 3-50 g of sodium sulfate and 1-30 g of methanol, and adding 5-15 g of de-ionized water and stirring evenly; then adding derivatization reagent, and adding de-ionized water to fully fill 100 g; then stirring evenly. The sulfonamide test paper is short in detection time, low in detection cost; the detection result is rapidly obtained through observing color change visually, thus the sulfonamides residue can be detected rapidly and efficiently.

Description

technical field [0001] The invention relates to the technical field of analysis and detection, in particular to a sulfonamide detection test paper. Background technique [0002] Sulfonamides are a kind of broad-spectrum antibacterial drugs, which are widely used in animal husbandry production. They are mainly effective in the prevention and treatment of animal diseases. They can treat fowl cholera, fowl typhoid, fowl paratyphoid, fowl pullorum, chicken infectious rhinitis, Arizona disease in turkey, etc. In addition, it also has a good effect on various coccidiosis and leukocytozoon disease in poultry. Although sulfa drugs are widely used, at the same time, the significant toxic and side effects of these drugs have also aroused widespread concern. For example: affect the function of the urinary system, cause crystalluria, hematuria and other reactions and carcinogenicity. Sulfonamides are absorbed and distributed in various tissues throughout the body, with the highest con...
