Biomaterials offer alternative opportunities to build sustainable environment compared to synthetic polymeric materials. Here, we utilized a naturally occurring and plentiful biopolymer, chitin, for the studies on interactive phenomena of a reactive textile dye, Remazol Orange (RO), from aqueous solution. The functional groups and crystallinity of chitin were examined by Fourier transform infrared spectroscopy (FT-IR) and x-ray diffraction (XRD) study. Scanning electron microscopy (SEM) and thermogravimetric analysis (TGA) were employed for the exploration of morphology and thermal stability of chitin. In order to investigate the effects of pH, contact time and initial RO concentration, batch studies were performed at room temperature of 25°C. Chitin exhibited a highly pH controlled reversible interaction with RO. RO was bounded 116.3 milligram per gram of chitin at pH 2.0 within 90 minutes of continuous shaking whereas 98.45% (w/w) RO were immediately unbounded from the chitin surface when the in-situ environment was changed at pH 10. Langmuir adsorption isotherm and pseudo-second order kinetic plot indicate homogeneous chemisorption and uniform monolayer of dye molecules on chitin surface. The findings from this study will certainly add value to analytical research leading to advanced applications in separation science and technology.

In the ocean, complex interactions between natural and anthropogenic radionuclides, seawater, and diverse marine biota provide a unique window through which to examine ecosystem and trophic transfer mechanisms in cases of accidental dissemination. The nature of interaction between radionuclides, the marine environment, and marine species is therefore essential for better understanding transfer mechanisms from the hydrosphere to the biosphere. Although data pertaining to the rate of global transfer are often available, little is known regarding the mechanism of environmental transport and uptake of heavy radionuclides by marine species. Among marine species, sponges are immobile active filter feeders and have been identified as hyperaccumulators of several heavy metals. We have selected the Mediterranean sponge Aplysina cavernicola as a model species for this study. Actinide elements are not the only source of radioactive release in cases of civilian nuclear events; however, their physicochemical transfer mechanisms to marine species remain largely unknown. We have targeted europium(III) as a representative of the trivalent actinides such as americium or curium. To unravel biological uptake mechanisms of europium in A. cavernicola, we have combined radiometric (γ) measurements with spectroscopic (time-resolved laser-induced fluorescence spectroscopy, TRLIFS, and X-ray absorption near-edge structure, XANES) and imaging (transmission electron microscopy, TEM, and scanning transmission X-ray microscopy, STXM) techniques. We have observed that the colloids of NaEu(CO)·nHO formed in seawater are taken up by A. cavernicola with no evidence that lethal dose has been reached in our working conditions. Spectroscopic results suggest that there is no change of speciation during uptake. Finally, TEM and STXM images recorded at different locations across a sponge cross section, together with differential cell separation, indicate the presence of europium particles (around 200 nm) mainly located in the skeleton and toward the outer surface of the sponge.
