[中文摘要]
|
以粉煤灰为主要原料,调整补充适量的Al(OH)3和Na2SiO3·H2O,负载并掺杂适量稀土镧元素和有机模板剂,与NaOH等水热合成出粉煤灰吸附剂。对所得产品进行苯酚吸附测试,结果表明,镧负载粉煤灰基吸附剂对苯酚的去除率达到88.9%。通过这一利用,不但粉煤灰的环境污染问题可得到缓解,而且可做到资源综合利用。

This research
takes fly ash as the main material , supplies
Al(OH)3 and Na2SiO3 · H2O properly, adulterates some lanthanum and organic stencilent and mixes them with NaOH
to make fly ash sorbent by hydrothermal synthetic
reaction. Then, using phenol adsorption to test the products, it shows that
the phenol removal rate of fly-ash base sorbent
with lanthanum reaches 88.9%. At the same time, pollution of fly ash not
only can be solved, but also can be turn it into treasure, and can be
utilized it effectively by this ways and means.
