| titleOfInvention | Pretreatment method for analysis of trace amounts of heavy metals in automotive adhesives |
| abstract | The present invention relates to a pretreatment method for the analysis of trace amounts of heavy metals contained in automotive adhesives (epoxy watch adhesives, synthetic ink paste adhesives, vinyl chloride adhesives, urethane adhesives, silicone adhesives, etc.), and more particularly, trace amounts of heavy metals. In the pretreatment process for analyzing the step, the step of thermally decomposing the adhesive sample in detail using a heating plate and nitric acid, perchloric acid, diethyldiocarbamic acid, bromothymol blue solution and methyl isobutyl ketone, evaporation drying, heating Through dissolution and dilution, it is formed into lead (Pb) chelated compound and then extracted with methyl isobutyl ketone, discarding the aqueous layer, taking MIBK layer, and treating this solution with nitric acid to improve the analysis of heavy metals up to ppm level. Of pretreatment method for analysis of trace amounts of heavy metals contained in automotive adhesives to be. |
