As-prepared material with large pores and high surface area was used to remove Orange G dye from aqueous solution. Adsorption experiments were carried out as batch studies at variety of contact times, pH, initial dye concentrations, temperatures and salt concentrations. Langmuir and Freundlich isotherm models were employed to simulate the equilibrium data of anionic dye. It was found that the equilibrium data were well represented by the Langmuir isotherm, yielding maximum monolayer adsorption capacity of 189 mg/g. Experimental data were analyzed using pseudo-first order and pseudo-second order kinetic models and obtained results indicated that kinetics followed a pseudo-second order equation.","authors":[{"authorName":"KAVEHArzani","id":"457c8afa-ec07-41ee-b031-f27bf2c3c195","originalAuthorName":"KAVEHArzani"},{"authorName":"BEHDADGhaderiAshtiani","id":"2266076d-98a2-403b-ad7e-2bbf41690381","originalAuthorName":"BEHDADGhaderiAshtiani"},{"authorName":"AMIRHOSSEINHajiAboutorabKashi","id":"a2665494-f0d8-4ee2-9ff9-3baa057f236e","originalAuthorName":"AMIRHOSSEINHajiAboutorabKashi"}],"categoryName":"|","doi":"10.3724/SP.J.1077.2012.12050","fpage":"660","id":"3e6d7515-223f-487f-abc6-d7ea735a9193","issue":"6","journal":{"abbrevTitle":"WJCLXB","coverImgSrc":"journal/img/cover/WJCLXB.jpg","id":"62","issnPpub":"1000-324X","publisherId":"WJCLXB","title":"无机材料学报"},"keywords":[{"id":"ecefe846-6832-4b60-be4f-295502f57533","keyword":"CMK-3;

The advantages of this method are as follows: Firstly, statistical information for innerdiameter distribution of open nanotubes can be obtained; Secondly, the method based on the adsorption process in inner cavities is of importance for investigation of other physico-chemical processes inside the cavities of carbon nanotubes. And finally, if combining with other characterization methods, complete structural information for cavity can be acquired and these basic parameters are important for theoretical investigations and practical applications of carbon nanotubes.","authors":[],"categoryName":"|","doi":"","fpage":"1317","id":"12b0b9d2-d465-465c-815b-aa95fbb5aff0","issue":"15","journal":{"abbrevTitle":"CSB","id":"93e93b22-e268-4660-889e-9c13ce861f8e","issnPpub":"1001-6538","publisherId":"CSB","title":"Chinese Science Bulletin"},"keywords":[{"id":"8f4a1e63-2666-4b8e-abcb-993e93b9e678","keyword":"carbon nanotubes (CNTs);innerdiameter distribution;gas adsorption;method;adsorption isotherm;walled carbon nanotubes;hydrogen storage;nanofibers","originalKeyword":"carbon nanotubes (CNTs);innerdiameter distribution;gas adsorption;method;adsorption isotherm;walled carbon nanotubes;hydrogen storage;nanofibers"}],"language":"en","publisherId":"1001-6538_2001_15_1","title":"Evaluation of diameter distribution of inside cavities of open CNTs by analyses of nitrogen cryo-adsorption isotherm","volume":"46","year":"2001"},{"abstractinfo":"In this work, the pyromellitic dianhydride (PMDA)-grafted P-cyclodextrin (P-CD) microspheres have been prepared for the removal of lead and cadmium metal ions in aqueous solution by a batch-equilibration technique.

Due to their high specific surface area (327.1 m(2)/g), large mesopore volume (0.68 cm(3)/g), and the presence of high affinity surface hydroxyl groups, am-ZrO2 nanoparticles demonstrated exceptional adsorption performance on both As(III) (arsenite) and As(V) (arsenate) without pre-treatment at near neutral condition. At pH 7, the adsorption kinetic is fast and the adsorption capacity is high (over 83 mg/g for As(III) and over 32.4 mg/g for As(V), respectively). Under low equilibrium arsenic concentrations (C-e at 0.01 mg/L, the maximum contaminant level (MCL) for arsenic in drinking water), the amount of arsenic adsorbed by am-ZrO2 nanoparticles is over 0.92 mg/g for As(III) and over 5.2 mg/g for As(V), respectively. The adsorption mechanism of arsenic species onto am-ZrO2 nanoparticles was found to follow the inner-sphere complex mechanism. Testing with arsenic contaminated natural lake water confirmed the effectiveness of these am-ZrO2 nanoparticles in removing arsenic from natural water. The immobilized am-ZrO2 nanoparticles on glass fiber cloth demonstrated an even better arsenic removal performance than dispersed am-ZrO2 nanoparticles in water, paving the way for their potential applications in water treatment facility to treat arsenic contaminated water body without pre-treatment.
