泥炭作为吸油材料的试验

为了研制一种理想的吸油剂,对泥炭、秸秆、锯末和改性泥炭用作吸油材料进行了对比试验.结果表明,未改性的风干泥炭吸油效果好于秸秆和锯末,而且是藓类泥炭吸油效果好于草本泥炭;对于同一类型的泥炭,中细纤维结构的吸油量高于中粗纤维结构的;与未改性的风干泥炭相比,不论采用物理方法还是物理化学方法进行改性,改性后泥炭的吸油效果均好于改性前的.试验证明了泥炭可以作为一种吸油材料,尤其是改性后的泥炭更是一种效率高、成本低、环保型的吸油材料.

Experiment on peat used as oil sorbent

Raw peat,cornstalk,sawdust and modified peat whose properties had been changed were respectively tested to develop a sort of perfect oil cleanup sorbent. The results show that air dried raw peat is superior to cornstalk and sawdust, and sphagnum peat is better than herbaceous peat in the aspect of absorbing oil; the amount of oil absorbed by peat with middle-thin fiber is higher than that absorbed by peat with middle-thick fiber. Moreover, modified peat, changing properties whether by physical or by physicochemical method, can both absorb more oil than air-dried raw peat. So peat is proven to be a kind of effective oil sorbent, especially the modified peat is a kind of perfect oil sorbent with high efficiency, low cost and little pollution.
