“…Two kinds of calixarenes have recently been used to prepare SPME fibers by sol-gel technology, and these have demonstrated high sensitivity and selectivity to aromatics and chlorinated aromatic compounds such as chlorophenols and organochlorine pesticides and their metabolites, which in turn leads to low detection limits (ng/L) [10][11][12][13][14][15].…”

A novel fiber coated with sol-gel (5,11,17,23-tetra-tert-butyl-25,27-dihydroxy-26,28-diglycidyloxycalix [4]arene/hydroxy-terminated silicone oil; diglycidyloxy-C[4]/OH-TSO) was prepared for use with headspace solidphase microextraction (HS-SPME) combined with gas chromatography (GC) and electron capture detection (ECD), which was applied in order to determine nine chlorobenzenes in soil matrices. Due to the improved fiber preparation, which increases the percentage of calixarene in the coating, the new calixarene fiber exhibits very high extraction selectivity and sensitivity to chlorine-substituted compounds. Various parameters affecting the extraction efficiency were optimized in order to maximize the sensitivity during the chlorobenzene analysis. Interferences from different soil matrices with different characteristics were investigated, and the amount extracted was strongly influenced by the matrix. Therefore, a standard addition protocol was performed on the real soil samples. The linear ranges of detection for the chlorobenzenes tested covered three orders of magnitude, and correlation coefficients >0.9976 and relative standard deviations (RSD) <8% were observed. The detection limits were found at sub-ng/g of soil levels, which were about an order of magnitude lower than those given by the commercial poly(dimethylsiloxane) (PDMS) coating for most of the compounds. The recoveries ranged from 64 to 109.6% for each analyte in the real kaleyard soil matrix when different concentration levels were determined over the linear range, which confirmed the reliability and feasibility of the HS-SPME/ GC-ECD approach using the fiber coated with diglycidyloxy-C[4]/OH-TSO for the ultratrace analysis of chlorobenzenes in complex matrices.

“…Instrument detection limits ranged from 0.6 µgl -1 (DEHP) to 3.16 µgl -1 (4-NP) and the LOQs varied from 1.9 µgl -1 (DEHP) to 10.44 µgl -1 (4-NP) as presented in Table 4. The LODs and LOQs values are adequate for environmental monitoring of the target compounds and low enough compared to previous work on the analytes of interest (Fatoki and Noma, 2002;Yuan et al, 2002;Cortazar et al, 2005;Zhou et al, 2005;Kayali et al, 2006;Ling et al, 2007) taking into account the complexity of the samples and the low sample amounts used. For wastewater and river samples, the LODs achieved in the present work were at similar levels or lower than those obtained in previous studies with GC-MS (Yuan et al, 2002;Cortazar et al, 2005;Kayali et al, 2006).…”

“…Some of them are priority-considered pollutants in wastewater due to their terrible toxicity for humans and aquatic organisms and have been included in the lists of priority and prerequisite monitored pollutants in many countries. 7 There have been several methods to determine phenols, among which spectrometric detection is a common and typical one, such as the spectrophotometric reaction with 4-aminoantipyrine, yielding a total phenol value, not permitting the identification of different phenols. 6,7 However, it should be noticeable that multi-component phenol compounds are often found in water in the form of homologous or isomeric compounds, which have similar structure and property at a low concentration level.…”

The electrochemical characteristics of multi-component phenolic pollutants, such as phenol (Ph), hydroquinone (HQ) and 4-nitrophenol (4-NP), were investigated on boron-doped diamond (BDD) film electrode by differential pulse voltammetry (DPV) technique. A simple and feasible platform was accordingly established for the direct and simultaneous determination of these three phenolic pollutants. Results showed that, Ph, HQ and 4-NP gave obvious oxidation peaks on BDD electrode at the potential of 1.24, 0.76 and 1.52 V, respectively. Each of them displayed good linear relationship between their oxidation peak currents and their corresponding concentrations in a rather wide range coexisting with one or two of the other phenolic pollutants. The detection limits of Ph, HQ and 4-NP were estimated to be as low as 1.82×10-6 , 1.67×10 -6 and 1.44×10 -6 mol•L -1 , respectively. Therefore, a promising direct and simultaneous electrochemical determination method of multi-component phenolic pollutants in wastewater samples was constructed successfully on BDD electrode with advantages being rapid, simple, convenient, sensitive, in situ and inexpensive.
