Two kinds of in-situ deposited ion imprinted polymers (IIPs) using electropolymerization method were presented for electrochemical detection of trace cadmium in water, which are ion imprinted polypyrrole/reduce graphene oxide modified glassy carbon electrode (IIPpy/rGO/GCE) and ion imprinted polyo-phenylenediamine/reduced graphene oxide modified glassy carbon electrode (IIPoPD/rGO/GCE). Electrochemical analysis of cadmium on the two modified electrodes was investigated by square wave anodic stripping voltammetry (SWASV) under the optimized conditions. The experiment results showed that IIPpy/rGO/GCE had wider linear range (1-100μg/L) and IIPoPD/rGO/GCE possessed lower detection limit (0.13 μg/L). The two kinds of modified electrodes are both green, simple, reused and compatible for trace cadmium detection in water with highly selectivity.

A novel electrochemical sensor based on electropolymerized ion imprinted poly (o-phenylenediamine) PoPD/electrochemical reduced graphene (ERGO) composite on glass carbon electrode (GCE) was fabricated for selective and sensitive determination of trace Cd(II) in water. ERGO was first deposited on the surface of GCE by electrochemical cyclic voltammetry (CV) scanning to enhance the electron transport activity at electrode surface. The ion imprinted polymer (IIP) of imprinted PoPD was then in situ electropolymerized on ERGO via CV scanning with oPD as functional monomer and Cd(II) ions as template, following removal of the template using electrochemical peroxidation method. The obtained imprinted PoPD/RERGO composites were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-ray energy spectroscopy (EDS) for the observation of their morphologies and components. The electrochemical behavior of the imprinted PoPD/ERGO/GCE was performed by CV and SWASV. The fabricated sensor of the imprinted PoPD/ERGO/GCE showed a good selectivity toward target Cd(II) ions in the presence of other heavy metal ions. Under the optimized experimental conditions, the sensor exhibited a good linear relationship between SWASV stripping peak values and Cd(II) concentration in the range of 1 to 50 ng/mL, with the limit of detection as 0.13 ng/mL (S/N = 3). The proposed electrochemical sensor of imprinted PoPD/ERGO/GCE was successfully applied for trace Cd(II) determination in real water samples.

Rich Internet Application(RIA) is a new kind of Internet applications, it can provide users with more strong interactivity, faster response and a richer user experience. There is a growing tendency for e-commerce systems with good user experience which is developed by RIA. RIA and Flex technology has been introduced in this paper. Based on the analysis of the disadvantages of the traditional e-commerce sites, we put forward a Flex application technology development of e-commerce sites.

In digital image processing algorithms transform the image of the matrix has a wide range of applications, all of the geometry of the transform, pixel color transform, convolution or transform images they can use the same principle to achieve the transformation matrix. At the same time to avoid the use of a separate matrix for each, respectively, to achieve the effect of code, the use of a particular matrix can be achieved over the past cumbersome and complex algorithms. The paper describes the matrix in the image principle innovativly put forward the BrightnessMatrix, ContrastMatrix.
