摘要:Abstract(#br)The method of closed-loop recycling counter-current chromatography (CLR CCC) with multiple sample injection is proposed for the separation and concentration of a target component of a mixture. Analytical expressions are developed to describe the CLR CCC separations w...

摘要:... This study is based on the selective separation of Pb-Sn, Sn-Cu, and Cu-Zn alloys, where supergravity separation was used to concentrate precious metals (i.e., Ag, Au, and Pd) from PCBs in Cu-Zn alloy and final residue. The temperature and gravity coefficient were found t...

摘要:Abstract(#br)The determination of background concentration of PM 2.5 is important to understand the contribution of local emission sources to total PM 2.5 concentration. The purpose of this study was to exam the performance of baseline separation techniques to estimate PM 2.5...
