摘要
本文使用扫描电镜(SEM)、傅里叶变换红外光谱(FT-IR)、X-射线衍射(XRD)以及X-射线光电子能谱(XPS)等方法,对弗洛斯坦连续电镀锡溶液中产生的锡泥的组成及物相进行了分析。结果表明,在锡泥中主要含有C、O、S及Sn等元素。锡泥经水洗后,其中含有的原电镀液中的成分被溶解于清洗液中,锡泥主要由锡的化合物及少量的苯酚磺酸盐组成。通过XPS窄幅扫描表明,Sn 3d5/2谱峰位于486.9eV位置,对应于元素锡的四价氧化态。锡泥中含有的主要成分为SnO2。
The analysis methods, which consisted of scanning electron microscopy （SEM）, X-ray diffraction （XRD）, Fourier infrared spectrum （FT-IR） and X-ray photoelectron spectroscopy （XPS）, were used to characterize the tin slurry produced in the process of Ferrostan continuous electrolytic tin solution. From the results, it was shown that there existedC, O, S and Sn in the tin slurry. Through cleaning by deionized water, the main content of the slurry was tin compound and a small quantity o{ phenol sulfonate for the compositions of the original electrolyte were dissolved to the water. The XPS narrow scanning spectra showed that the peak of Sn 35/2 existed at 486.9 eV, which corresponded to the quadrivalence tin element （SnO2）.
