Rapid butyl xanthate detection kit and detection method thereof

Abstract

The invention discloses a rapid butyl xanthate detection kit which comprises a kit body (1), and an extracting reagent pre-preparing pipe (2), a color-producing reagent pre-preparing pipe (3), a test tube rack (4), a pipettor, forceps (5), a washing bottle (6) and a trace cuvette (7) which are arranged inside the kit body, wherein the extracting reagent pre-preparing pipe (2) is a round-bottle test tube with an opening in the top, a butyl xanthate extracting reagent is placed inside the extracting reagent pre-preparing pipe (2), the opening in the top of the extracting reagent pre-preparing pipe (2) is sealed by adopting a syringe needle silicon gel stopper (8); the color-producing reagent pre-preparing pipe (3) is a round-bottom screw-tap test tube with an opening in the top, a butyl xanthate color-producing reagent is arranged inside the color-producing reagent pre-preparing pipe (3), the opening in the top of the color-producing reagent pre-preparing pipe is sealed by adopting a leakage-preventing silica gel pad (9), and degreasing cotton (10) is placed in a pipe opening inside the color-producing reagent pre-preparing pipe (3). The rapid butyl xanthate detection kit disclosed by the invention can be used for rapidly and stably realizing site detection, and has a good effect.

Description

technical field [0001] The invention relates to a kit, in particular to a rapid detection kit for butyl xanthate and a detection method thereof. Background technique [0002] Butyl xanthate (potassium salt, sodium salt), commonly known as "xanthate", is a light yellow to yellow powder or stick-shaped solid at room temperature, toxic and flammable, and is a floating substance with relatively strong collection ability. Agents and rubber vulcanization accelerators, because they will exist in the tailings wastewater from the flotation of colored sulfide ores. Butyl xanthic acid is discharged into the surface water along with the wastewater, which will cause the water body to have a peculiar smell and cause certain toxicity to aquatic organisms, livestock and humans. Therefore, butyl xanthic acid in mineral processing wastewater has been listed as an environmental protection monitoring One of the projects, in the "Environmental Quality Standards for Surface Water" (GB 3838-2002)...

AI Technical Summary

Problems solved by technology

[0003] Since 2008, the Ministry of Environmental Protection has included the monitoring of organic substances in surface water in the monthly routine monitoring items. Butyl xanthic acid is mainly spectroscopically determined according to the copper reagent cuprous spectrometer specified in the national standard method GB / T 5750.8-2006. Photometric method is used for detection, and there are also literature reports using ion selective electrode method and extraction ultraviolet colorimetric method, but the existing methods have cumbersome processing steps, long processing time, low sensitivity and poor method reproducibility, and butyl xanthic acid is relatively unstable at the same time , needs to be measured as soon as possible in a short period of time, and there is no method for on-site rapid detection
