This paper investigates a new type of carbonbased electrodes, which were equipped with graphite and activated carbon fiber composite, to improve the performance of electrosorption. The results indicated that the highest desalination efficiency achieved 55 % and the optimal condition was 1.6 V voltage, 60 min retention time and 1.0 cm electrode distance. Freundlich isotherms successfully fitted with the respective behavior of the composite electrode and provided theoretical evidence for the desalination performance improvement. Applied in real black liquor of refined cotton, the graphite and activated carbon fiber composite electrodes achieved high removal efficiency for conductivity (59 %) and COD Cr (76 %). Similar removal performance was also observed in sodium copper chlorophyll wastewater, and removal efficiency was 37 % for conductivity and 14 % for COD Cr . For the first time, this research demonstrated the biodegradability improvement in real industrial wastewater via electrosorption treatment, suggesting a potential pretreatment technique for high-salinity wastewater.

The actively Q switched laser performance of the mixed Nd:Lu 0.5 Y 0.5 VO 4 crystal was demon strated for the first time. At the pump power of 7.26 W, the minimum pulse width of 46.6 ns was obtained at the pulse repetition rate of 5 kHz with the cavity length of 80 mm, and the single pulse energy and peak power were calculated to be 42 µJ and 901.3 W, respectively.
