“…For this purpose, methods have already been developed, such, ion exchange [14], solvent extraction [15], precipitation [16][17], and adsorption [18][19][20][21]. These techniques are usually performed using conventional or non-conventional adsorbents, especially, zeolites, and iron(III) hydroxide [22][23][24][25]. However, adsorption is a technique of choice for the removal of dissolved elements as Cr(VI) from aqueous solutions.…”

The adsorption of chromate ions H2-yA (y = 1, 2, and A = CrO42–) on iron(III) hydroxide was conducted as a function of adsorbent mass, solution pH, and hydration time. The surface complexation technique, based on the examination of the chromate distribution between the solid and liquid phases, was adopted to predict the adsorption mechanism. To specify stoichiometry of the chromate surface complexes, the proton (n > 0), and hydroxyl (n < 0) ion-exchange was evaluated at a pH range of 2–12. The obtained “n” values are ranging between -1 and 1. As a result, the sorption process involved specific chemical interaction with surface sites, resulting in 1H+ and 1OH– release of the adsorbate molecule. The surface species identified were ; ; ; ; ; ; ; and . The logarithmic values of their complexing constants were: log K00 = 1.81 ± 0.04; log K11 = -3.53 ± 0.07; log K21 = -1.03 ± 0.23, log K1-1 = 7.15 ± 0.14 and log K2-1 = 9.62 ± 0.53. The results showed that the chromate adsorption on Fe(III) hydroxide was of electrostatic and chemical nature at pH lower than 5.5, and only of chemical nature at pH superior to 5.5. Taking into account these considerations, Fe(III) hydroxide could be considered an excellent sorbent for the removal of Cr(VI) from wastewater solutions.

Статья посвящена последним тенденциям в области исследования и применения биосурфактантов -поверхностно-активных биомолекул, производимых микроорганизмами. Биосурфактанты рассмотрены как альтернатива синтетическим поверхностно-активным веществам. Дан краткий обзор основных принципов получения, скрининга и характеристики биосурфактантов, их физико-химических свойств. Проанализированы представления о взаимосвязи между свойствами биосурфактантов и их использованием. Особое внимание уделено исследованиям, связанным с потенциальным применением биосурфактантов, актуальными проблемами при их производстве и внедрении в реальном секторе экономики. Описаны современное состояние мирового рынка биосурфактантов и перспективы его дальнейшего формирования.
