Automated separation and measurement of 226Ra and trace metals in freshwater, seawater and fracking water by online ion exchange chromatography coupled with ICP-MS

Comparison of radium‐226 separation methods based on chromatographic and extraction resins for its determination by ICP‐MS in drinking waters

“…As explained previously, protocol P5 was time‐consuming due to both the co‐precipitation and resin separation steps, involving a substantial labor cost and explaining a higher final cost than for the other methods. For the five methods tested, the cost of labor could be reduced by optimizing the conditioning of the columns, the sample loading, the rinses, and the 226 Ra elution flow rates and volumes through automation using for example automated syringe modules 29,30 …”

“…For the five methods tested, the cost of labor could be reduced by optimizing the conditioning of the columns, the sample loading, the rinses, and the 226 Ra elution flow rates and volumes through automation using for example automated syringe modules. 29,30 The quantity of waste per processed sample (Table 1) could also be considered in final cost estimations. Not considering processed samples as waste, volumes of produced waste varied between about 23 and 430 ml.…”

Cyanoremediation of heavy metals (As(v), Cd(ii), Cr(vi), Pb(ii)) by live cyanobacteria (Anabaena variabilis, and Synechocystis sp.): an eco-sustainable technology

“… 3 The toxicity of HMs (As( v ), Cd( ii ), Cr( vi ), Pb( ii )) has become a global issue because of their presence in the food chain, as human beings are the top consumers in the food chain. 4 HMs in drinking water can cause chronic effects, including nausea, vomiting, diarrhea, kidney failure, cognitive impairment, thyroid abnormalities, muscle weakness, and cancer. 5 Chronic exposure to Cd( ii ), Cr( vi ), Ni( ii ), and Pb( ii ) in humans may cause kidney and bone damage, adverse respiratory effects, contact allergies, and neurotoxicity, respectively.…”

Screening of synthesis conditions for the development of a radium ion-imprinted polymer using the dummy template imprinting approach

“…However, among commercial resins, rare succeed alone to selectively extract Ra 2+ from the other alkali or alkaline-earth cations that are much more concentrated in the samples [2,3]. Most extraction procedures, followed by an ICP-MS analysis, employ the AG50W-X8 cation exchange resin alone [4][5][6][7] or in combination with a strontium specific resin (Sr resin) [8][9][10][11][12][13][14],…”
