AbstractMicroporous metal-organic frameworks (MOFs) based on lanthanide metal ions or clusters represent a group of porous materials, featuring interesting coordination, electronic, and optical properties. These attractive properties in combination with the porosity make microporous lanthanide MOFs (Ln-MOFs) hold the promise for various applications. This review is to provide an overview of the current status of the research in microporous Ln-MOFs, and highlight their potential as types of multifunctional materials for applications in gas/solvent adsorption and separation, luminescence and chemical sensing and catalysis.

In this paper, it is proposed to use the biomass of microalgae Chlorella sorokiniana as a biosorbent for wastewater treatment, as well as an oral sorbent. Biosorbents are capable of adsorbing both organic and inorganic compounds, including heavy metals. The sorption capacity depends on the type of aquatic plant and microalgae strain. The use of microalgae and aquatic plants as biosorbents for pollutant treatments is discussed in the introduction part. The biomass of microalgae Chlorella sorokiniana was chosen as the object of this study. The cultivation conditions (temperature, light, pH and aeration) and the optimal biomass harvesting parameters are presented. Dehydration of biomass was carried out in two ways: IR-drying and freeze-drying. The obtained samples were tested for the ability of the biomass to extract heavy metal ions (zinc, cadmium, zinc, copper) from standard solutions. The initial concentration of heavy metal ions in the working solutions was 10 mg/l. Results show that the lyophilized samples demonstrated up to 99.9% of heavy metal removal efficiency. The paper also presents the composition of Chlorella sorokiniana biomass, in which up to 40.97–41.87% are proteins. The analysis of the amino-acid composition showed a ratio of essential to non-essential amino-acids higher than 0.8. All the above results confirm the possibility of using microalgae biomass as an oral sorbent and as an additive in the production of functional foods.

Two novel 12-connected 3D porous lanthanide–organic frameworks have been synthesized by the reaction of bipyridine-carboxylate ligand bpydbH2 and lanthanide metal ions. Both of them show a high proton conduction behavior as well as their composite membranes.
