To reduce the toxicity of mesoporous materials in the process of preparation and improve its order, onion-like mesoporous silica was successfully assembled through hydrothermal synthesis, using tetraethoxysilane as silica source, P123 surfactant as template, and environment-friendly span80 as auxiliary agent in aqueous media at different mass ratios (span80/P123 = 10, 15, 20, 25 and 30 %). Multiple characterization technologies such as FT-IR, SEM, TEM and N 2 isothermal adsorption-desorption suggested that the onionlike mesoporous materials could be formed when the mass ratios of span80/P123 = 10, 15, 20, 25 %. When the mass ratio of span80/P123 reached 30 %, the material was with foam morphology. The adsorption experiments showed that all samples exhibited high ability to absorb methylene blue (MB). Our success in synthesizing the onion-like mesoporous materials using environment-friendly agent could provide a new route to the morphology control of mesoporous materials.

A new dispersive liquid-liquid microextraction procedure combined with UV-visible spectrophotometry is described for sensitive and selective determination of rhodamine B. Various analytical parameters such as pH, extraction and dispersive solvents type and volume, sample volumes, and extraction time were optimized. Matrix effects of concomitants were also examined. Preconcentration factor was found to be 330. Detection limit was calculated as 2.1 μg L −1 . The relative standard deviation was found to be 4%. The validation of the developed procedure was checked by the addition/recovery tests. The procedure was successfully performed to the determination of trace levels of rhodamine B in drug, ink, food, cosmetic product, and waste waters.

In this study, adsorption of Pb(II) and Mn(II) ions from aqueous solutions onto dehydrated hazelnut husks carbon (DHHC) was carried out batchwise in order to obtain optimal values for several effective parameters such as pH, contact time, dosage, and initial concentration. The adsorption of both Pb(II) and Mn(II) ions was found to be highly dependent on pH, which were optimum values of 4.5 and 5.5, respectively. The adsorption of both ions reached equilibrium conditions at 60 min. The experimental data of both ions were best fitted with the Langmuir model by maximum adsorption capacities of 133.3 and 44.8 mg g À1 for Pb(II) and Mn(II), respectively. Kinetic studies showed that Pb(II) and Mn(II) adsorption onto DHHC abided well by pseudo-second-order model.
