磷钨酸水合物

磷钨酸水合物用途

【用途一】
用作生化试剂及色谱分析试剂
【用途二】
各种生物碱、含氮碱、酚、蛋白质、蛋白胨、氨基酸、脲酸、脲、血液和碳水化合物的试剂。生物染色。（１）有机合成反应的催化剂，在国内主要取代环境污染严重的液体酸类，如硫酸、氢氟酸、三氯化铝等，在国外则是一种新型的固体酸催化剂而受到很多合成领域的关注；　（２）生化试剂及色谱分析试剂：在药物的分离、鉴定、化学毒物的毒理学研究，法医学鉴定以及生物材料的分析中，广泛用作沉淀剂、氧化剂和显色剂，如分析阿托品、氨基比林，奎宁、普鲁卡因和可卡因等，利用薄层色谱法检出类固醇需用磷钨酸的乙醇溶液；通过生成磷钨酸的分析鉴定水果、蔬菜、植物和食品中的含磷杀虫剂。
