Right organic compound, is widely present in shellfish, insect and fungi.Shitosan be chitosan moiety it is deacetylated after product
Thing, by its abundant functional group's composition, biocompatibility, biodegradability and nontoxicity, shitosan shows to dyestuff
Powerful adsorption capacity, has good application prospect in dye wastewater treatment.However, the proportion and mechanical strength of shitosan
Relatively low and unstable to soda acid, these weak points limit the popularization of its application.
To improve the performance of shitosan, can be fixed in and organo-mineral complexing adsorbent, example are prepared on inorganic matter
Such as patent " preparation method of Chitosan Supported by Bentonite compound adsorbent " (application number CN201410553345.X) and patent "
Plant the flyash chitosan compound adsorbing agent preparation method for the treatment of dyeing waste water " (application number CN201610102612.0).But,
Because the compatibility of shitosan and inorganic matter substrate is poor, the interface cohesion of the compound for obtaining is not good, have impact on absorption property.
Substrate is carried out organically-modified, compatibility can be improved, so as to improve absorption property, such as " environment-friendly chitosan intercalation is multiple for patent
Close bentonite adsorption agent and process for producing same " (application number CN201010107961.4), the use of chemical reagent is but increased, also make system
Standby technique becomes complicated.Shell is the biomineralization material of a class organo-mineral complexing, and calcium carbonate accounts for 95% in its composition, its
It 5% is the organic matters such as protein and polysaccharide to remaining, and this special construction makes shell powder innately have preferable organic compatibility.
The content of the invention
The purpose of the present invention is, using the natural organic compatibility of shell powder, to overcome existing chitosan compound adsorbing agent system
The shortcoming of standby technique and deficiency, there is provided a kind of preparation method and applications of shitosan-oyster shell whiting compound adsorbent.
The preparation method of shitosan-oyster shell whiting compound adsorbent, comprises the following steps successively：

4) shitosan of 1~5 mass parts is mixed with the diluted acid that the mass concentration of 100 mass parts is 0.1%~10%, is stirred
Mix, prepare chitosan solution；
5) the certain mass ratio of oyster shell whiting under fast stirring, is accounted in shitosan, chitosan solution is slowly dropped to
In oyster shell whiting suspension, shitosan is set to be separated out on oyster shell whiting surface；
6) silk cover filtering is used, much filtrate is rinsed with water, washes away the calcium salt of reaction generation；
7) much filtrate after washing is dried at 40 DEG C~100 DEG C, grinding obtains shitosan-oyster shell whiting composite adsorption
Agent.
Above-mentioned technical proposal can also provide some following preferred embodiments：
Step 2) described in calcining heat be 150 DEG C~400 DEG C.
Step 4) described in acid be hydrochloric acid, nitric acid, formic acid, acetic acid, oxalic acid, citric acid, pyruvic acid or lactic acid.
Step 5) described in shitosan account for oyster shell whiting ratio be 5%~50%.
The shell includes mussel shell, pearl shell, oyster shell, scallop shell, clam shell or freshwater mussel shell.The above method
The shitosan of preparation-oyster shell whiting compound adsorbent can be used as the adsorbent of congo red, saturated extent of adsorption scope
It is 140.5mg/g~358.5mg/g.
It is an advantage of the invention that raw material sources are extensively, process is simple, operating condition is gentle, and the adsorbent of preparation possesses excellent
Absorption property, it is with low cost, it is environmentally friendly, with good economic and social benefit.
