The introduction of analytical techniques allowing rapid, selective, sensitive, and reliable determination of aqueous pollutants is of crucial importance for the protection of the environment. This critical review summarizes the advanced analytical techniques suggested over the last ten years together with already established methods, and evaluates whether they are fit for wastewater quality assessment considering the area of application, interferences, limit of detection, calibration function, and precision. The key parameters of wastewater quality assessment are: total organic carbon (TOC), chemical oxygen demand (COD), biochemical oxygen demand (BOD), organochlorines (AOX), nitrogen, phosphorus, sulfur, and toxicity. Chromatography and capillary electrophoresis, photocatalytic oxidation with semiconductor nanofilms and atomic emission spectrometry, optical fibre sensors and chemiluminescence, amperometric mediated biosensors and microbial fuel cells, respirometry and bioluminescence measurements are just part of the proposed wastewater analyst's toolkit. The diversity of fundamental phenomena and the captivating elegance of interdisciplinary applications involved in the development of wastewater analytical techniques should attract the interest of a wide scientific audience including analytical chemists, chemical physicists, microbiologists and environmentalists. To conclude, we suggest a laboratory set up for the analysis of wastewaters from the pulp and paper industry.

“…Down sizing of sample preparation techniques for liquid-phase separations has been studied along with the effective on-line coupling of the miniaturized sample preparation technique to LC separation methods [56][57][58][59][60][61][62][63][64][65]. As similar to the successful applications of particulate chemically-bonded stationary phases in LC to an extraction medium in solid-phase extraction, several types of fiber-packed capillaries were introduced as the extraction medium in microscale sample preparation techniques Chromatograms for the separation of dodecane, tetradecane and hexadecane on a short polymer-coated fiber-packed capillary column with the rapid temperature programming.…”

Miniaturization is a key technological approach to realize high performance separation systems that have several important features required in modern analytical methods. A smaller scale of the stationary phase synthesis enables a systematic analysis of the retention behavior and also a more efficient development of novel stationary phases in liquid chromatography. Development of microscale sample preparation technique has been regarded as a valuable supporting approach to the development of microscale separation methods. Effective on-line coupling of the microscale sample preparation and separation allows an efficient and rapid analysis without a loss of sensitivity for most of the analytical separations. In this review, development of the miniaturized separation techniques and the applications have been described from the view point of the authors' research group, including the development of novel stationary phase, microscale sample preparation techniques for liquid and gas sample matrices.

“…The phosphate analysis method was designed on the basis of formation of phosphoantimonylmolybdenum blue (PAMB) reported originally by Murphy and Riley. [16][17][18][19] The ion pair can also be entrapped by a C-18 (ODS) column and can be extracted with polar solvents such as methanol and CH 3 CN. [13][14][15] In our previous work, ion pair formation was employed for the spot test for phosphate analysis, where PAMB was entrapped on the packing material in a mini column with a blue color band formed in the column.…”

The concentration of phosphate in surface and oligotrophic waters is sometimes below the detection limit of conventional analytical methods. In this work, a membrane extraction method using a hydrophilic PTFE (H-PTFE) membrane filter was developed to detect trace level phosphate. Phosphoantimonyl-molybdenum blue (PAMB) was prepared under conventional conditions. The PAMB was made to react with hexadecyltrimethyl ammonium (HTMA) ions by ultrasonication in an ice bath to form an ion pair of PAMB and HTMA. The ion pair was entrapped on a H-PTFE filter by filtration, and the ion pair on the filter was extracted with CH 3 CN. When 10 mL of CH 3 CN was used as the extraction solvent for 100 mL of water sample (10 times of concentration factor), 0.80 mg PO 4 L À1 (0.26 mg P L À1 ) was successfully detected using a conventional spectrophotometer equipped with a 5 cm cell. The total phosphorus could also be detected after oxidation with potassium peroxosulfate.
