“…The cellulose phosphate-based Whatman P81 membrane, which is considered a strong cation exchange membrane, was proposed by some authors [6,[10][11][12][13][14][15] as a new binding phase in DGT measurements of Ba, Cd, Co, Cu, Hg, Mn, Ni, Mn, Pb, U and Zn in different types of water (river water, petroleum-produced formation water, treated acid mine drainage water). The reuse of this binding agent was suggested by Li et al [10] for up to four times for the Cd and Cu determination.…”

Spent coffee grounds (SCG) immobilized in agarose gel are proposed as a novel binding agent for application in the Diffusive Gradients in Thin films (DGT) technique for the determination of Cd, Cu, Ni, Pb and Zn in waters. The SCG-agarose gel was characterized by Scanning Electron Microscopy, Energy Dispersive X-ray Spectrometry and Porosimetry by nitrogen adsorption. Elution of analytes from the binding agent was effectively performed with 2 mol L −1 HCl. The effects of key DGT parameters (e.g. immersion time, ionic strength and pH) were evaluated with a deployment of DGT devices (DGT-SCG) in synthetic solutions with ionic strengths between 0.005 mol L-1 and 0.1 mol L-1 and within a pH range of 3.5 to 8.0. The results were in excellent agreement with the predicted theoretical curve for mass uptake. Consistent results were found for solutions with ionic strengths between 0.005 mol L-1 and 0.1 mol L-1 and within a pH range of 3.5 to 8.0. The DGT-SCG performance was also evaluated in two spiked river water samples (Corumbataí and Piracicaba river) with satisfactory uptake values (C DGT-SCG /C sol) between 0.74 to 1.53. The proposed DGT-SCG opens opportunities for using residual biomass as binding phase in the DGT technique, showing low costs in production and complying with "green" technology approaches.

“…The use of ion exchange membranes as DGT binding phases has advantages of excellent mechanical strength, flexibility, reuse and easy preparation, in comparison with other types of binding phases (Huang et al 2016d;Li et al 2002Li et al , 2005a. Li et al (2002) utilized commercially available solid cellulose phosphate membranes (Whatman P81) as DGT binding phase to determine Cu and Cd, and this type of DGT has been extended to measurement of other metals, such as Cd, Cu, Pb, Zn, Co, Ni, Mn, Ba, Hg and U species (Colaço et al 2014;de Oliveira et al 2012;Larner and Seen 2005;Mengistu et al 2012;Pedrobom et al 2017). In addition, the Whatman DE 81 with amino functional groups has been applied for the measurement of U species and Cr(VI) in waters (Li et al 2006;Pedrobom et al 2017;Suárez et al 2016).…”

“…A diffusion gradients in thin-films (DGT) technique has been proposed by Davison and Zhang (Davison and Zhang 1994;Turner et al 2014) as an in-situ, simple and long-term sampling tool for the assessment of labile metals speciation. The DGT technique is based on the selective diffusion across a diffusion layer (such as polyacrylamide hydrogel (Davison and Zhang 1994), cellulose acetate dialysis membrane (Li et al 2003), cellulose membrane (de Oliveira et al 2012), chromatography paper (Larner and Seen 2005), agarose gel (Dong et al 2014), nylon membrane (Wang et al 2016) and polyethersulfone (PES) membrane (Fan et al 2016)) and dissociation of metal species in a binding layer comprising binding agents (such as Saccharomyces cerevisiae (Pescim et al 2012), amberlite IRP-69 ion-exchange resin (Zhang et al 2014), amorphous zirconium oxide (Ding et al 2010), titanium dioxide (Bennett et al 2010), copper ferrocyanide (Li et al 2009), precipitated ferrihydrite (Luo et al 2010), XAD18 resin (Chen et al 2013) and molecularly imprinted polymer (Dong et al 2014)). Dahlqvist et al (2002) were the first to use the DGT technique, with a Bio-Rad ChelexÒ100 resin as the binding agent, for Ca 2þ and Mg 2þ measurements in freshwater.…”

Environmental contextLow availability of calcium (Ca2+) in soils is one of the major factors in Ca2+ deficiency of plants and physiological plant disorders. A device based on functionalised silica was developed for in-situ measurement of the available Ca2+ in soils. Application of the proposed device to measure available Ca2+ may help to develop and improve agricultural practices. AbstractCalcium is an ion of particular interest due to its importance in plant nutrition and soil structure. A novel device of diffusion gradients in thin-films (DGT) based on the benzo-crown ether-functionalised silica (BCES) as the binding agent and the polyethersulfone (PES) membrane as diffusive layer (BCES-DGT) was developed for in-situ sampling of available calcium (Ca2+) in freshwater and soil samples. The performance characteristics of the BCES-DGT device were assessed. The BCES was prepared using the sol-gel process and characterised by Fourier transform infrared spectroscopy, scanning electron microscopy, thermal gravimetric analysis and N2 adsorption–desorption. Results evinced that BCES was obtained successfully with a rough wrinkled surface and good specific surface area of 111.3 m2 g−1. The diffusion coefficient of Ca2+ ions in PES membrane was found to be 1.23 × 10−6 cm2 s−1 at 25 °C and was independent of pH in the range of 3–10 and ionic strength (as pNaCl) from 1 to 3. The high binding capacity of BCES binding gel for Ca2+ ions was determined to be 9822.4 ± 452.9 μg Ca2+/disk and was conducive to the deployment of long-term or high concentration. The BCES-DGT device can accurately measure the concentrations of Ca2+ over wide ranges of ionic strengths (1–3 as pNaCl) and pH (5–10). There was no significant interference on the uptake of Ca2+ by the BCES-DGT device at the tolerance limits up to 500 for Mg2+, Li+, HCO3−, H2PO4−, NO3− and SO42−, 250 for Sr2+, 2000 for K+ and 50 for fulvic acid. The results from BCES-DGT device were in excellent agreement with those measured directly using ion selective electrode in several water and soil samples. Field application in river water indicated that a good agreement was obtained between BCES-DGT value and mean grab sample measurements of Ca2+ and that the relative standard deviation of BCES-DGT measurement (4.7 %) was superior to that of grab sample measurements (13.5 %), suggesting that BCES-DGT was reliable for in-situ sampling and measurement of available Ca2+ with good accuracy and precision.
