2014年1月25日 · CaO is an important material because of its application as catalyst and effective chemisorbents for toxic gases. In this research CaO nanoparticles were prepared via direct thermal decomposition method using Ca (OH)2 as a wet chemically synthesized precursor.

The synthesized nanoparticle was characterized by scanning electron microscope (SEM), Fourier-transform infrared spectroscopy (FTIR), X-Ray fluorescence (XRF) and X-ray diffraction (XRD).

其中，KOH为3678 cm-1，NaOH在3637 cm-1, Mg (OH)2为3698 cm-1，Ca (OH)2为3644 cm-1。 在实际应用中，无机物的红外光谱可以用来干什么呢？ 举个简单的离子，对于氧化物而言，其表面的结构羟基和许多应用都有密切关系（比如催化，生物医用等）。 而这些表面羟基采用XRD肯定是定不出来的，这个时候采用红外进行表征就具有优势了，特别是原位红外，可以研究在不同温度下表面羟基的变化情况，进而跟其性能联系起来。 另外，红外光谱和XRD相结合对于样品的定 …

2013年10月1日 · We review the Fourier-transform infrared (FTIR) spectroscopy of side-chain COO − groups of Ca 2 + -binding proteins: parvalbumins, bovine calmodulin, akazara scallop troponin C and related calcium binding proteins and peptide analogues.

2008年10月31日 · 傅里叶变换红外光谱（FT-IR）成功用于三元混合物中碳酸钙相（方解石，文石，球v石）的同时定量分析。 从具有KBr的纯方解石，文石和球ate石粉的FT-IR光谱中，方解石在713 cm（-1），球v石在745 cm（-1），713和700 cm（ -1）为文石，经测定。 为了克服吸收带重叠，开发了基于比尔定律的一组方程。 还建立了检测极限，发现在713 cm（-1）处每mm（2）的沉淀为1.1 x 10（-4）mg方解石，每mm（2）的3.6 x 10（-4）mg文石在700 cm（-1）时， …

2021年12月27日 · Fourier Transform Infrared Spectroscopy (FTIR) is a fast, low-cost, accurate and widely available method in universities and service and research laboratories [8], [38], [39]. FTIR scans the sample with a specified range of the electromagnetic radiation spectrum at the mid-infrared wavelength [72].

2021年11月4日 · In this study, citric acid (CA)-coated magnetite Fe3O4 magnetic nanoparticles (Fe3O4@CA MNPs) for use as draw solution (DS) agents in forward osmosis (FO) were synthesized by co-precipitation and characterized by Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), dynamic light scattering (DLS), transmission ...
