“…IIPs are now largely involved in sensors devices in which they act as recognition phases and can include special functionalities like fluorescent probes [23][24][25]. Whatever the application, the use of IIPs is based on the selective recognition of the template ion in competitive and sometimes complex media: environmental water [26,27], sea water [28], wine [29], human plasma [30].…”

“…In order to overcome these drawbacks, many researchers developed surface-molecular imprinting techniques [23][24][25][26], and tried to make the imprinted caves to lie on the surfaces of solid particles. The surface imprinted materials are more effective for recognizing the template molecules.…”

Methacrylic acid was first graft-polymerized on the surfaces of micron-sized silica gel particles in the manner of "grafting from" using 3-methacryloxypropyl trimethoxysilane as an intermedia, obtaining the grafted particle polymethacrylic acid PMAA/SiO(2). By adopting the novel surface-molecular imprinting technique put forward by us, cytisine molecule-imprinted material MIP-PMAA/SiO(2) was prepared with ethylene glycol diglycidyl ether as crosslinking agent. The binding characteristics of MIP-PMAA/SiO(2) towards cytisine was investigated in depth with both batch and column methods and using matrine and oxymatrine as two contrast alkaloids, which with cytisine coexist in sophora alopecuroides and their chemical structure is similar to cytisine to a certain extent. The experimental results show that the surface-imprinted material MIP-PMAA/SiO(2) has excellent binding affinity for cytisine (20.1 g/100 g of binding capacity), and it is more important that MIP-PMAA/SiO(2) has very high recognition selectivity for cytisine in relation to the two contrast alkaloids. The selectivity coefficients of the grafted particles PMAA/SiO(2) (non-imprinted material) for cytosine in relation to matrine and oxymatrine are only 1.03 and 1.06, respectively, displaying no recognition selectivity for cytisine. However, after imprinting, the selectivity coefficient of MIP-PMAA/SiO(2) for cytisine in respect to matrine and oxymatrine are remarkably enhanced to 12.08 and 15.05, respectively.

Atomic absorption spectrometry (AAS) is a well‐established technique for the quantitative determination of elements in environmental materials at trace and ultratrace levels. AAS is an optical atomic spectrometric technique based on the measurement of the specific absorption originated from the free, unionized atoms in the gas phase. For transferring the analyte to free atoms, different types of atomizers are in use, out of which the flame and the graphite furnace are the most often used atomizers. Typical detection limits of flame AAS (FAAS) are of the order of 1–100 μg L −1 , making it a perfect tool for the determination of minor and trace elements, at least for contaminated samples. Graphite furnace AAS (GFAAS), offering detection limits which are about a factor of 20–200 lower than for FAAS, is the standard method for many trace elements especially for background values, and for unpolluted samples, such as freshwater and biological materials. AAS in its conventional configuration is a single element technique, which has to be used in a sequential mode when more than one element has to be determined. However, there are commercial instruments available, that can be used for the determination of six to eight elements simultaneously. While most manufacturers provide instruments working with line sources, one manufacturer has commercialized high‐resolution instruments working with continuum sources (HRCS‐AAS).
