化学类本科生毕业论文-火焰原子吸收光谱法测定涂料中的铬.doc

摘要涂料的质量直接关系到人类的健康和生存环境,检测并控制涂料中有毒有害物质的组成及含量对环境保护起着十分重要的作用。本文简述涂料工业的现状以及国内外涂料中有毒有害物质检测技术的基本情况。选定三种涂料样品进行处理,通过实验对它们的液体部分和颜料部分中铬的总含量进行研究,实验中应用火焰原子光谱吸收法对重金属铬的含量进行了测定,通过测定分析表明此方法精确度,准确度较高,其选择性也较好,操作简便。实验结果表明,本文所分析的苯丙漆、苯丙纳米漆、FC漆三种涂料中铬的含量都没有超过国家限定标准,涂料中“可溶性”铬的限量为≤60mg/kg。关键词:火焰原子吸收光谱法;涂料;铬含量的测定AbstractThequantityofthecoatingrelatestodirectlythehumanhealthexiststheenvironment。Seefromthedevelopmenttrend,Thebuildingcoatingwilldeveloptowardenvironmentalprotectiontype,lowpoisontypedirection,binesthecontrolcoatinginsideispoisonousharmfulconstitutesandcontainsthedealtorisestotheenvironmentalprotectionmateriallyveryimportantfunction。ircumstanceinexaminationinpoisonousandharmfulmaterialininsideindomesticandinternationalcoatings。Thistextistheliquidtopainttocolorpartinsidechromegrossresearchwithdeal。Applyingtheflameatomspectrumabsorbsthemethodtocontaintotheheavymetalschromethedealproceededthemeasurement,uracy,uratedegreeishigher,itsselectivityisbettertoo,,:FAAS;paint;Determinationofchromium目录第一章绪论-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------9第二章实验内容-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
