A B S T R A C TSepiolite was selected and studied for the adsorption of octenylsuccinate in the waste solution resulting from the production of octenylsuccinic starch. Scanning electron microscopy showed that sepiolite had a high surface area, and Fourier transform infrared spectroscopy indicated the formation of bonds between sepiolite and octenylsuccinate. The effects of reaction temperature, initial octenylsuccinate concentration, pH, adsorption time, and sepiolite dosage on adsorption efficiency (%AE) were examined by single-factor experiments. Significant parameters were further optimized by Box-Behnken response surface methodology. The theoretical optimum value of 100% was obtained when the initial octenylsuccinate concentration, pH, adsorption time, and sepiolite dosage of 20 mL solution were 0.048 mol/L, 3.12, 5.40 h, and 771.32 mg, respectively. Under these optimum conditions, the real %AE was 99.07%.

Late Pleistocene Palaeoenvironmental Variations from Marine Isotope Stages 5 and 4: Small Mammals at Artazu VIII Site (Arrasate, Northern Iberian Peninsula)

Sites corresponding to Marine Isotope Stage 5 (MIS 5) and MIS 4 like Artazu VIII, with a continental record but no hominin imprints or carnivores activities, are very scarce in the Iberian Peninsula. The Artazu VIII cave fill (Arrasate, northern Spain) was discovered in 2013 and is presented here for the first time, including detailed stratigraphic and sedimentological descriptions of the differentiated 12 levels, as well as an ordered chronology of most levels, covering at least 36,000 years. In addition, the small mammal assemblage yielded a total of 8,129 identifiable skeletal remains corresponding to 14 taxa. The conditions inferred from the ecological preferences of the small mammal associations have been correlated with four different stages and substages from MIS 5c to MIS 4 in which the woodland mass expanded and retreated, depending on the relative temperature and humidity in each period. Finally, considering the species variability and estimated palaeoenvironment, a comparison with the NGRIP δ 18 O curve and other sites with the same chronology has been performed, showing that Artazu VIII is one of the few deposits attributable to the Marine Isotopic Stages previously mentioned and the only one that correlates to the Greenland Interstadial 18 from the Iberian Peninsula.
