This invention provides a metallocene complex and the preparation method thereof and a catalyst composition. This catalyst composition comprises a metallocene complex represented by formula (I) and an organic boron salt. Compared to the prior art, the catalyst used in this invention, which is the metallocene complex represented by formula (I), does not contain a group bonding between the heterocyclic fused cyclopentadienyl ring and the transition metal, and the coordination space of the central metal has a large opening degree. Therefore, the catalytic activity for more sterically hindered monomers is higher, and the comonomer incorporation is also higher. Furthermore, the metallocene complex represented by formula (I) used in this invention is a heterocyclic ring fused cyclopentadienyl ligand. Heterocyclic rings have relatively strong electron-donating capacity. By fusing a cyclopentadienyl group using heterocyclic rings, it is possible to change the electronic effect of the metal center and in turn increase the activity of catalyst. Therefore, by using the metallocene complex represented by formula (I), it is possible to prepare copolymers of ethylene with other olefins at high activity and high comonomer incorporation, and it is also possible to catalyze the polymerization of styrene and substituted styrene at high syndiotacticity and high activity.

Provided in the present invention are a cisplatin complex which is formed by cisplatin and a polymer of the structure of formula (I), and the method for preparing the cisplatin complex, which comprises a coordination reaction of cisplatin with the polymer of the structure of formula (I) in an aqueous medium, resulting in the cisplatin complex. The cisplatin complex has good biocompatibility and is degradable; the side chain of the polymer is grafted with polyethylene glycol, thus the prepared cisplatin complex has good solubility; when the cisplatin complex is dissolved in an aqueous medium, the cisplatin is protected by a hydrophilic polyethylene glycol chain segment and a hydrophobic amino acid chain segment, which can effectively avoid a sudden release of the cisplatin due to the influence of the blood circulation system after intravenous injection, thus improving the stability of the cisplatin complex. Additionally, the carboxyl contained in the cisplatin complex provided in the present invention is sensitive to pH values and tends to deprotonate in a low pH environment, which favors the release of the drug and improves the efficiency of the drug.

The present invention provides a method for detecting biochemical oxygen demand. Active sludge, surface water, domestic waste water, or industrial waste water comprising microorganism is taken as a water sample with microorganism in the method provided by the present invention. The water sample with microorganism is cultivated to obtain a microorganism film. The blank water sample and the target water sample are made to pass through the microorganism film respectively. The dissolved oxygen reduction current values of the blank water sample and the target water sample are detected. The difference value between the dissolved oxygen reduction current value of the target water sample and that of the blank water sample is obtained. On the basis of the difference value and the predetermined standard curve, the biochemical oxygen demand of the target water sample is acquired. The method provided by the present invention adopts active sludge, surface water, domestic waste water, or industrial waste water comprising microorganism as the water sample with microorganism. The environmental adaptability of the prepared microorganism film is strong, so that one or more of tap water, well water, atmospheric water, or ground water may serve as medium to maintain the physiological activity with no need of providing a buffer solution system.

A method for extracting and separating a rare-earth element. Cations and anions in a quaternary ammonium ionic liquid extractant, that is, 2-ethylhexyl phosphate mono-2-ethylhexyl acrylate trialkyl-ammonium and phosphate di(2-ethylhexyl) phthalate trialkyl-ammonium, are reacted with rare-earth ions to form neutral complex molecules, also, a collaborative effect and a competitive effect are present between the cations and the anions in the quaternary ammonium ionic liquid extractant in a rare-earth element extraction process, the separation factor for the rare-earth element is thus increased. The method for extracting and separating the rare-earth element provides great interfacial phenomena in the extraction process, generates no emulsification, obviates the need for extractant saponification, and provides increased separation factor for rare-earth elements, and particularly increased separation factor for heavy rare-earth elements. In addition, the rare-earth element extraction and separation method is of reduced extraction acidity, of reduced stripping acidity, and of reduced acid consumption.
