The AHS was characterized by means of SEM, BET, FTIR and XPS. Different experimental parameters were evaluated in batch adsorption experiments to determine the optimal adsorption conditions. Adsorption kinetics shows that the adsorption rate is well represented by the pseudo- secend-order rate model, and the Langmuir model gives the best fit adsorption isotherm. The Langmuir maximum adsorption capacities were fotmd to be 21.14 mg/g for Cu2＋, 32.74 mg/g for Pb2＋, 68.03 mg/g for MB and 263.16 mg/g for MG, respectively, while the adsorption capacities could be maintained above 90% even after ten adsorp- tion-desorption cycles. The experimental results show that AHS could be applied to treat both industrial and munici- pal wastewaters.展开更多

The SHS modified with mercaptoacetic acid（MHS） was characterized using FTIR, SEM, and XPS. The results indicated that the --SH group was present on MHS, and after Pb2＋ adsorption, the absorption value of the characteristic peak of the --SH group decreased. The adsorption and desorption properties of this func- tionalized material were investigated as well as the influences of parameters, such as pH value, type of desorption reagent, dosage, flow rate and maximum sample volume. The Pb2~ adsorption of MI-IS reached a maximum with pH〉5. The experimental data of Pb2＋ adsorption using MHS were fitted using the Langmuir isothermal adsorption model, and a maximum adsorption capacity of 61.54 mg/g was obtained. This was much higher than the adsorption capacity of SHS before modification with the thiol group. After adsorption, MHS was desorbed using a 0.2 mol/L HC1 solution, and the percent of desorption was higher than 99%. MHS was used as a solid-phase extractant in the analysis and determination of Pb2＋ content in food and water samples, and the enrichment times achieved 150-fold.展开更多
