Recently, basing on optical-feedback cavity-enhanced absorption spectroscopy (OF-CEAS) technology, a research team led by Prof. ZHANG Weijun from Hefei Institutes of Physical Science (HFIPS), Chinese Academy of Sciences (CAS) successfully detected OH radicals at 2.8 μm wave length with a distributed feedback (DFB) diode laser.
According to a new report on Langmuir, a kind of iron-based carbon microsphere, which was fabricated by tobacco waste liquid (TWL) and waste iron residue (WIR), was successfully developed to removal Cadmium ion (Cd(II)) from water and soil.
Recently, a research team from Hefei Institutes of Physical Science (HFIPS), Chinese Academy of Sciences (CAS) developed a new algorithm in the direction of near-infrared spectroscopy technology, which is used for improving the transfer efficiency of near-infrared qualitative analysis models between instruments.
