High-Quality UV-Vis Spectrum Signal Reconstruction Algorithms Based on Binary Search
Hong-qiu ZHU, Hao-nan HU, Guo-liang ZHENG, Can ZHOU, and Yong-gang LI
In the background of high zinc, when the concentration of trace polymetallic ions is simultaneously measured by spectroscopy, the energy radiation of the light source of the micro-spectrometer is not uneven, and different ions in the mixed solution can selectively absorb the ultraviolet-visible light at different bands

Synthesis and Spectroscopic Characterizations on the Complexation of Three Different Metal Ions Ba(Ⅱ), Ni(Ⅱ), and Ce(Ⅲ) with Atenolol Drug Chelate
EI-Megharbel Samy M, Altalhi Tariq, Salem Alruqi Abdullah Ayad, and Refat Moamen S
Three types of metal ions barium(Ⅱ), nickel(Ⅱ) and cerium(Ⅲ) complexity of ATN drug have been prepared and characterized using molar conductance method, FT-IR, electronic, and 1H-NMR analysis measurements. The chemical and physical results for all atenolol complexes are agreement with the speculated structures. For the
