七十年代,国外的选矿工作者开始把衰减全反射(Attenuated Total Reflection,缩写为ATR)技术用于研究浮选药剂与矿物的作用机理。 ATR技术与透射光谱技术相比,有如下优点: 1.可以记录低吸收能力物质光谱; 2.可以记录强吸收能力物质光谱,这种样品对于透射光谱的测定需要制备难以制备
In the seventies, mineral concentrates abroad began to use Attenuated Total Reflection (ATR) technology to study the mechanism of action of flotation reagents and minerals. ATR technology has the following advantages over transmission spectroscopy: 1. Can record low-absorbance substance spectra; 2. Can record strong absorbance substance spectra that are difficult to prepare for transmission spectroscopy
