文摘
- •
PP-g-CaSiO3@SiO2 was synthesized and used to absorb DBP in aqueous solution.
- •
Large surface area and Si
OH on PP-g-CaSiO3@SiO2 improved the adsorption of DBP.- •
Six-caned hydrogen bond was formed between Si
OH of PP-g-CaSiO3@SiO2 and DBP hydrolysate.- •
A low temperature and low pH is beneficial for the adsorption of DBP.
- •
PP-g-CaSiO3@SiO2 costs low, can be easily prepared without any pollutants, and reused.
