Description
Technical field
A kind of method that the present invention relates to biological adsorption agent utilizing leaves of plants preparation to purify benzene, it is former that it belongs to a kind of environmental protection
The production method of ecological ideas biological adsorption agent.
Background technology
WHO is set to strong carcinogen benzene, and benzene can be with leukemogenesis and aplastic anemia
Also generally acknowledged by medical circle.Subacute benzolism can occur after sucking higher concentration benzene in a short time, giddy, headache, weak, mistake occur
Symptoms such as dormancy, menoxenia, and aplastic anemia, acute leukemia can occur, the anemia showing as developing rapidly, go out
Blood, infection etc..Benzene is more some more to male to the hazard ratio of women, and the women of child-bearing age suck benzene for a long time can cause menoxenia, pregnancy period
Women's Contact benzene time, the sickness rate of pregnancy complications can significantly increase, result even in fetal congenital abnormalities.
Calendar year 2001, the Chinese Consumers' Association is organized in Beijing and two places, Hangzhou and enters the Indoor Environmental Condition after part finishing
Go test of entering the room, polluted found that half numerical example exists benzene, account for the 43.3% of total sample number.
At present the processing method of benzene has the non-equilibrium plasma method of purification, ventilation method, plant purification method, absorption method, quiet
Electric precipitation method etc..These methods or poor effect adsorption rate are low, also or be easily generated saturated or generate as the most smelly with harmful gas
Oxygen etc..
Summary of the invention
Present invention aim to address the method that existing purification room benzene pollutes also exist that adsorption rate is low, absorption is the most saturated and
The technical problem easily generated with harmful gas, it is provided that a kind of method of biological adsorption agent utilizing leaves of plants preparation to purify benzene.
The present invention solves that above-mentioned technical problem the technical scheme is that
A kind of method of biological adsorption agent utilizing leaves of plants preparation to purify benzene, it specifically comprises the following steps that
(1) sampling: collect discarded civil and military cypress fallen leaves；
