性质:(一)利用酸溶液去除钢铁表面上的氧化皮和锈蚀物的方法称为酸洗。氧化皮、铁锈等铁的氧化物(Fe3O4,Fe2O3,FeO等)与酸溶液发生化学反应,形成盐类溶于酸溶液中而被除去。酸洗用酸有硫酸、盐酸、磷酸、硝酸、铬酸、氢氟酸和混合酸等。最常用的是硫酸和盐酸。酸洗工艺主要有浸渍酸洗法、喷射酸洗法和酸膏除锈法。一般多用浸渍酸洗法,大批量生产中可采用喷射法。钢铁零件一般在10%~20%(体积)硫酸溶液中酸洗,温度为40℃。当溶液中含铁量超过80g/L,硫酸亚铁超过215g/L时,应更换酸洗液。常温下,用20%~80%(体积)的盐酸溶液对钢铁进行酸洗,不易发生过腐蚀和氢脆现象。由于酸对金属的腐蚀作用很大,需要添加缓蚀剂。(二)为了消除硅藻土载体表面吸附,减少色谱峰拖尾,载体在使用前需进行酸洗或碱洗处理。酸洗是把载体用6mol/L盐酸浸煮2h或浓盐酸加热浸煮30min,过滤,用水洗至中性,烘干。酸洗可除去表面上的铁、铝、钙、镁等杂质,但不能除去硅醇基。酸洗载体适宜于分析酸性样品。
