吸附

While the adsorptions of l-propanol and 1-Br-propane at 100 癈 give rise to 1-propoxy species, which mainly converted to propanal at higher temperature. IR spectrum arising from the interaction of propene with the catalyst at 100 癈 shows the IR bands of allyl alcoholate and isopropoxy species. As the temperature was increased to 150 癈, the bands ascribable to the adsorbed acetone and acrolein were observed. Based on these results, it is suggested that isopropoxy species is one of the intermediates for SOP to acrolein over MoPO/SiO2 catalyst.

When pH is 10, adsorption time is 30 min, dosage of bone char is 0.6 g/L, the original concentration of As in drinking water is 0.5 mg/L, As removal can reach 95.2%. The adsorption behavior is fitted both with Langmuir and Freundlich isotherm. The adsorption mechanism is supposed to be Ca—OH functional groups combined with anion. And there may occur the co-precipitation between calcium hydrogen arsenate and hydroxylapatite in the aqueous solution, and ions also exchange. The saturation adsorption capacity of As reaches 4.688 mg/g. Indexes of effluent are in good agreement with the WHO stringent drinking water standards (0.01 mg/L).
