of these metal complexes lies in the optoelectronics areas, such as light-emitting devices (LEDs)[7], chemosensors[8], and photovoltaic devices[9]. Among these complexes, cyclometalated platinum (II) complexes with a square- planar d8 electronic configuration, have displayed their potential applications in light-emitting devices[10-12]. Many cyclometalated homo- or hetero-leptic platinum (II......

A novel recovery technology of trace precious metals from waste water by combining agglomeration and adsorption ZOU Hua-sheng(邹华生), CHU Zhu-qiang(储著强), LIN Gang(林 岗) School of Chemical and Energy...: A novel and efficient technology for separating and recovering precious metals from waste water containing traces of Pd and Ag was studied by the combination of agglomeration and adsorption. The recovery......
rabbits in the exposed group. The concentration of six kinds of heavy metals in the blood of the rabbit increases after 16 weeks exposing to cigarette smoking. Three times of Hg, ten times of Se..., 0.804, 0.698, 0.034. 0.220 and 0.104 μg/mL in urine, respectively. Compared to the blank group, the variations of Sn, Ni and Cr were smaller than other metals, which indicated that lower......
