“…Torrades 63,64 discusses the detection and elimination of constant error component and interactive matrix interference in the AOX determination of adsorbable organic in bleached kraft paper pulp mill effluents and points out the need to use the total Youden blank test. Measurements were carried out in the presence of the matrix at two different levels of the test portion to avoid interactive interference.…”

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.

“…In order to overcome this problem, a previously developed methodology was used in this study 10–13. The methodology discusses errors in terms of a constant component to the analyte and/or matrix, an analyte proportional component, also dependent on the matrix (interactive component) and a third component depending solely on the matrix (direct interference).…”

A calibration methodology that enables validation of the analytical procedure used in those cases where no placebo or standard reference material is available is applied here. The total Youden blank is used to eliminate the constant error component, and analytical measurements in the presence of the matrix at two different levels of the test portion, in order to avoid its interactive interference, are made. Moreover, the results obtained in the determination of chemical oxygen demand following a closed re¯ux spectrophotometric method are compared with those obtained when a de®nitive analytical method is applied, in order to show the absence of direct interference from the matrix.

“…Among the pool of organic pollutants the chlorinated compounds are especially of interest due to their toxicity and persistence [1]. Especially the AOX, starting in Germany in the early 1980s, has become an important environmental parameter [8,9,10]. Chlorinated organic compounds have been determined in the environment for more than three decades.…”
