Technical field
The present invention relates to a kind of adsorbent, particularly to one using plant leaf blade as raw material, a kind of suction of modified preparation
Attached dose and method, belong to adsorbing material field.
Background technology
Along with developing rapidly of process of industrialization, many waste water of industrial discharge such as plating, ore dressing and process hides, waste gas and useless
Slag often results in the heavy metal pollution of water environment, heavy metal can not biodegradation, and live body in be enriched with, cause various disease
Disorderly with body, very harmful to organism.
The technique that efficiently separates being presently used for removing heavy metal ions in sewage has: at the exchange of precipitation, ion, electrochemistry
Reason, membrane technology, evaporation coagulation, reverse osmosis and electrodialysis etc., but the application of these technology is limited, closely by technique and economy sometimes
Over Nian, organism absorption by living is removed the method for heavy metal and has been caused concern, this method mainly utilize hyperaccumulative plant,
Algae and microorganism heavy metal have bigger absorbability to remove the heavy metal in waste water, but process dirt with the organism lived
Water is limited by Biomass and the growth characteristics of organism itself, and such method is also unsuitable for applying on a large scale the most so far.
Modified cellulose class adsorbent is one of important development direction of current cellulose functional high molecule material.Such adsorbent does not draws
Entering new pollutant, consume energy low, so there being important application in water processes, and being more easy to regeneration than adsorbent resin again, and
Stability is high, and adsorptive selectivity is special, and adsorbent price is far below adsorbent resin.
Prepare, for cellulose origin, a kind of Land use systems that adsorbent is abandoned biomass resource with Herba Plantaginis, and can realize
Utilize the problem that a kind of abandoned biomass resource is curbed environmental pollution.The present invention is using Herba Plantaginis as raw material, in isopropyl
Under the effect of alcohol, NaOH solution and citric acid solution, modification is prepared as a kind of biomass adsorbent.
Summary of the invention
The present invention is to provide a kind of method utilizing Herba Plantaginis modification to prepare adsorbent.The method passes through techniques below route
Realize:
