“…Heavy metals like Cu(II), Ni(II), and Cd(II) lead to many environmental problems and these toxic metals affect the human health seriously at even their low concentrations [1,2]. The removal of heavy metals has become a major problem since they do not have a biodegradable property naturally in the environment [1].…”

Poly(2-acrylamido-2-methyl-1-propanesulfonic acid-co-1-vinyl-2-pyrrolidone), P(AMPS-co-VP), hydrogel was prepared by free radical cross-linking polymerization method. Prepared hydrogel was used in the competitive removal of Cd(II), Pb(II) and Cu(II) ions from aqueous solution. The characterization of P(AMPS-co-VP) before and after sorption was carried out by the Fourier transform infrared spectroscopy, thermogravimetric analysis and scanning electron microscopy. Atomic absorption spectrometer was used to found the concentration of metal ions in the aqueous solution. The selectivity of P(AMPS-co-VP) was as follows: Cd(II)>Pb(II)>Cu(II). Kinetic study showed that competitive removal of heavy metal ions on poly(AMPS-co-VP) was in accordance with a pseudosecond-order model.

“…Существуют различные мнения по этому поводу. В некоторых сообщениях был показан более высокий потенциал поглощения металлов свободными водорослями по сравнению с иммобилизованными (Mehta, Gaur, 2005), в других (Petrovič, Simonič, 2016) -именно иммобилизованные клетки водорослей успешно поглощали тяжелые металлы. По данным Al-Rub et al (2004), как и в нашем исследовании, присутствие водорослей в альгинатной матрице увеличивало скорость поглощения тяжелых металлов и усиливало иммобилизацию стабилизирующих структур.…”

“…Например, в бинарном растворе Cd и Fe мешали друг другу в процессе их поглощения клетками Sargassum sp. (Mehta, Gaur, 2005), а также сорбции Сd, Ni и Cu клетками Chlorella sorokiniana, иммобилизованными альгинатом (Petrovič, Simonič, 2016). Металлы различаются в зависимости от их способности препятствовать сорбции других металлов (Mehta, Gaur, 2005).…”

Scenedesmus species, immobilized on alginate gel, was found effective in removing nitrate, atrazine, magnesium, phosphorus, zinc, oxadiazon, and triallate from groundwater in a continuous flow reactor. The laboratory‐scale experiments with synthetic groundwater, made of 8.8 mg/L NO3‐N and 90 µg/L atrazine, were performed at a hydraulic retention time of 7 days and the temperatures of 20 and 35°C. The highest uptake of nitrate and atrazine was observed at 20°C (97% and 70%, respectively). When tested in actual groundwater, 92% of nitrate, 100% of magnesium, 99.9% of phosphorus, and 92% of zinc were successfully removed at the end of 29 days’ treatment operations. The algal beads removed 100% of oxadiazon and triallate in the first 10 days, but some of the herbicides diffused back into the solution toward the end of the treatment process. Practitioner points Immobilized algae–alginate beads can remove nitrate, atrazine, oxadiazon, and triallate from groundwater in continuous flow reactor. The uptake rate of nitrate and atrazine is higher in room temperature (20°C). Same algae beads could be reused for herbicide uptake for the average of 10 days. The immobilized system is a natural sustainable alternative that can be used in groundwater pump and treat.
