Bacteria biochar adsorbent

A biochar-derived adsorbent preferably from Sargassum boveanum, macroalgae can be used for removing phenolic compounds, such as 2,4,6-trichlorophenol and 2,4-dimethylphenol, from aqueous solutions. The carbonization can improve the removal capability of the macroalgae adsorbent for such phenolic compounds with removal efficiencies of 60% or more from high salinity seawater and 100% from distilled water. The adsorption may occur through a mixed mechanism dominated by physisorption following pseudo second-order kinetics. The adsorption of the phenolic molecules may be spontaneous, endothermic and thermodynamically favorable.

METHODS AND USES OF ENCAPSULATED EXUDATES AND DRIED EUGLENA BIOMASS FOR BINDING METAL

A method of binding a target metal in solution. The method of binding a target metal comprises contacting a solution containing i) a target metal with ii) an encapsulated exudate of a culture of algal flagellate, or a fraction thereof; or an encapsulated dried Euglena biomass or a fraction thereof, to form a complex between the target metal, and the encapsulated exudate or fraction thereof, or the encapsulated dried Euglena biomass or the fraction thereof; and optionally separating the complex from the solution. The disclosure also relates to a biosorbent element, as well as methods of using same in binding a metal in solution.

Method of preparation and application of ion-keeper adsorbent

The invention belongs to the field of chemical separation, hydrometallurgy and resource recovery and provides a method for preparing and applying of ion-keeper adsorbent. By adjusting the pH to selective oxidation to achieve the oxidation of ferrous iron into ferric iron. Separates the iron after the hydrothermal reaction; By using of ion imprint “ion keeper” effect and biomass as raw materials, to prepare the adsorbent with internal rules, hierarchical pores and high selectivity. It can be used for deep purification of chromium solution, such as iron, aluminum, vanadium and other impurities in the solution; After the deep purification of chromium solution, then adjusting the pH, adding appropriate hydrating agent, by hydrothermal precipitation treatment of chrome, filtration, acid washing and calcination to obtain chromium oxide crystal. It achieves the purification of chromium, iron, aluminum and chromium. The recycling and comprehensive utilization of waste resources are also realized. The process is simple, the iron, aluminum, vanadium and other impurities are in the selective adsorption. Chromium solution after deep purification can be processed for high purity chromium products to provide technical support.
