General description
乙基紫是一种橄榄绿色粉末，属于三芳基甲烷染料。其颜色从黄色（pH 0.0）变为蓝色（3.5）。
Biochem/physiol Actions
乙基紫是一种阳离子三芳甲烷染料，是结晶紫的乙基同系物。这是一种普通的组织学和病理学染色。乙基紫已用于胰腺组织和弹性蛋白染色 ，用于检测革兰氏阴性菌 ，并用作阴离子表面活性剂的萃取-分光光度法测定试剂。 乙基紫诱导线粒体通透性。已用于铜的萃取和分光光度法测定。在 SDS-聚丙烯酰胺凝胶电泳中，乙基紫与阴离子染料锌试剂一起用于蛋白质的反离子染色。

In this study, a xylan/PVA/TiO2 composite was prepared and used for the photocatalytic degradation of dyes in solution. Fourier-transform infrared, X-ray diffraction, and X-ray photoelectron spectroscopic analyses confirmed that the xylan/PVA/TiO2 composite was successfully prepared. Furthermore, the composite was evaluated
