分离和提纯物质二者之间既有区别又有联系，物质的分离是将混合物中的几种组分各自分开，从而得到较纯净的物质。物质的提纯是将物质中混有的少复杂质转化成其他物质而除去。物质的分离通常采用物理方法，若采用化学方法，最后则需把分离开的物质再转化成原组分或指定物质。物

Material purification is the removal of less complex materials that are mixed in the material to other materials. Separation of substances is usually performed by physical methods. If chemical methods are used, the separated substances are finally converted back to the original or designated substances. Things
