“…They emphasized that any method for quantifying PAM in soil waters should be sensitive at low concentrations (<1 mg L -1 ) and insensitive to interferences such as dissolved salts and organic matter (OM). The analytical methods for aqueous PAM are generally based on (i) the chemical properties of amide groups in PAM assessed by N-bromination of the amides (Scoggins and Miller, 1979;Lu and Wu, 2001); (ii) the physical properties of the PAM solution determined by viscosity measurement ( Jungreis, 1981), flocculation-based methods (Lentz et al, 1996), or size exclusion chromatography (Hunt et al, 1988); (iii) the combined physical and chemical properties determined by turbidimetric methods (Allison et al, 1987) or polarography (Smith-Palmer et al, 1988); and (iv) methods based on total organic carbon (TOC) concentration and radioactive labeling (Ben-Hur et al, 1992;Entry et al, 2008). Most of these methods are complicated procedures that may require expensive laboratory equipment.…”

Concerns over runoff water quality from agricultural lands and construction sites have led to the development of improved erosion control practices, including application of polyacrylamide (PAM). We developed a quick and reliable method for quantifying PAM in soil extracts at low carbon content by using a turbidimetric reagent, Hyamine 1622. Three high-molecular weight anionic PAMs differing in charge density (7, 20, and 50 mol%) and five water matrices, deionized (DI) water and extracts from four different soils, were used to construct PAM calibration curves by reacting PAM solutions with hyamine and measuring turbidity development from the PAM-hyamine complex. The PAM calibration curve with DI water showed a strong linear relationship (r 2 = 0.99), and the sensitivity (slope) of calibration curves increased with increasing PAM charge density with a detection limit of 0.4 to 0.9 mg L -1 . Identical tests with soil extracts showed the sensitivity of the hyamine method was dependent on the properties of the soil extract, primarily organic carbon concentration. Although the method was effective in mineral soils, the highest charge density PAM yielded a more reliable linear relationship (r 2 > 0.97) and lowest detection limit (0.3 to 1.2 mg L ). Our results suggest that the hyamine test could be an efficient method for quantifying PAM in environmental soil water samples as long as the organic carbon in the sample is low, such as in subsurface soil material often exposed at construction sites.

“…doi: 10.2166/aqua.2013.032 In general, analytical methods for polymers include gas chromatography, high-performance liquid chromatography, mass spectrometry and a combination of these methods. In addition, the starch-triiodide method (Scoggings & Miller 1979), viscosity (Jungreis 1981), calorimetry (Hansen & Eatough 1987), turbidimetry (Clapper et al 1989), fluorescence spectrometry (Arryanto & Bark 1992), colloid titration (Gehr & Kalluri 1983), radioactive labeling (Nadler et al 1994), flow injection analysis (Taylor et al 1998), size exclusion chromatography (SEC) , nuclear magnetic resonance (NMR) spectroscopy (Chang et al 2002), fluorescence tagging (Becker et al 2004) and spectrophotometric determination using cationic dyes (Chmilenko et al 2004) were previously used for detection of polyacrylamide in surface water, wastewater, soil water and oilfield brines. The presence of salts, cations, anions, oil, humic acids, dissolved organic substances, and pH and temperature conditions has been shown to interfere with the sensitivity of these methods .…”

The goal of this study was to develop a method that uses UV-Vis spectroscopy for the determination of residual poiymer concentration water and environmentai samples. UV-Vis absorbance measurements are quick and simple and can be usefuily applied In research and practice. Five different polymers exhibiting a wide range of polymer characteristics were tested in the UV range of 200-300 nm. The incrementai increases in polymer concentrations corresponded to incrementai increases in absorbance measurements, and a strong iinear relationship was estabiished between the polymer concentration and the absorbance values. The method was successfully used in the determination of polymer concentrations in water sampies, as weii as in centrate samples coliected from a wastewater treatment plant.

The synthesis and characterization of a novel macroporous silica derived size exclusion chromatography (SEC) packing for quantitative analysis of high molecular weight (MW) polyacrylamide (PAM) are presented. Using this packing, a fast, sensitive and reproducible approach for quantitation of super high-MW PAM in demanding enhanced oil recovery (EOR) waters was developed and the effect of synthesis parameters on the properties of resultant materials was investigated. These parameters include salt addition, reaction temperature and duration, activation condition of functional groups on the silica surface, as well as the reaction cycles required for optimal silica modification. Moreover, SEC analysis conditions, such as mobile phase composition, flow rate, detection and sample preparation, were also explored and an optimal analysis protocol was developed. Under this optimized SEC analysis conditions, the synthesized macroporous materials proved satisfactory for quantification of PAM with average MW up to 22 million Daltons. An SEC analysis required less than few minutes with a detection limit of 1 ng, a linear response range of 0.1 to 75 mgIL with squared R value of 0.99 and reproducibility better than 9.2% RSD (relative standard deviation). The analysis of PAM in highly saline oilfield production water containing interfering high MW polymeric surfactants indicated the recovery ranges from 92.5% to 110.1% for 1.0 mgIL PAM and 94.2% to 103.8% for 50 mgIL PAM solution. This study presented for the first time that the reliable quantization of high MW PAM in highly demanding EOR waters can be achieved by SEC.
