摘要
有很多分析方法可用来测定颜料及中间体的纯度,如液相色谱、红外、紫外及可见光谱等等,对三种有机颜料PR176、PR188、PB60的纯度的分析测定方法进行了探讨与研究。主要对可见光谱方法进行了研究,因为其简便、经济、实时,适合于生产过程控制。根据颜料的性质,比较其在不同溶剂中的溶解度,确定合适的溶剂与合适的浓度,同时寻找适当的吸收峰。在此峰处,吸收强度与浓度存在线性关系。应用此线性关系对试样和标样的纯度进行比较,达到控制产品质量的目的。
In this paper, UV-visible spectrometric technique has been developed and applied to analysis of the purities of organic pigment-PR176, PR188, PB60. The development work included screening of solvents which can afford a suitable solubility and optimization of the conditions, such as concentration and the absorbance peak, which can afford the consistent, reproducible results. It has demonstrated that UV-visible spectrometric technique is simple and quick that it can be implemented for quality control in organic pigment production.
