Attapulgite Clay

Attapulgite clay (ATP) was modified by Silane coupling agent (KH-570) to creat more efficient sites for Cu(II) adsorption. The natural and KH-570 modified attapulgite clay were characterized by Fourier transform infrared spectrometer (FTIR) and SEM. The effects of various experimental parameters such as the amount of modifier, the quality of KH-570 modified ATP, adsorption time, adsorption temperature on Cu(II) adsorption onto KH-570modified ATP were studied in detail. The results showed that the 30% of modifier (The quality of the modifier mass fraction attapulgite) had the best adsorption capacity. When the dosage of modified attaplgite clay was 0.5g and the absorption time was 240min under 20°C, the adsorption rate of Cu(II) in wastewater approached 97%. Meanwhile, the type of absorption was Langmuir isotherm. Desorption experiments showed that the adsorption mechanism of KH-570 modified ATP to Cu(II) was the chemical adsorption.

A novel desulfurizer was prepared to remove the sulfide in MTBE. The performance of the desulfurizer was investigated by L18(2×37) Orthogonal Test. The desulfurizer for MTBE was prepared by the impregnating technique, in which the transitional metal Fe series and Ag series compounds were used as active components, and the modified attapulgite clay as the carrier. In order to get the optimum conditions to desulfurization in MTBE, IR, XRD, TEM, XPS technology were used to study the desulfurization mechanism. Compare the desulfurization characterize before and after the experiment. The result shows that the desulfurizer made by 8% Fe series compound and 2% Ag series compound, and roasted at 300°C for 3 hours. The Sulfur content in MTBE was reduced from 789mg/kg to 124mg/kg. The desulfurization rate was reached to 84.18% (in normal temperature and pressure.). The removal effect is obvious. The result of this study can be applied for Removal sulfide in MTBE.
