Technical field
The present invention relates to field of industrial waste water treatment, and in particular to a kind of 8- aminoquinoline modified starch chelating agent and its system Preparation Method.
Background technique
Aminoquinoline is a kind of important derivatives of quinoline, and the presence of conjugated structure becomes a kind of excellent ligand, Energy and Cu2+、Zn2+Etc. the chelate that many transition metal ions form solubility very little.Since aminoquinoline is N, N-type is of the same race The chelating agent of coordination atom can generate stable complex with close nitrogen metal.
Starch has many advantages, such as nontoxic, from a wealth of sources, cheap and biodegradable.Native starch is the height of glucose Aggressiveness contains a large amount of hydroxyl and glycosidic bond in molecular structure, can be obtained not by the modification of the method for physics, chemistry and biology Same modified starch.It there is no the report that modified starch chelating agent is prepared with aminoquinoline at present.
Summary of the invention
The object of the present invention is to provide a kind of preparation methods of 8- aminoquinoline modified starch chelating agent, to solve background skill Drawbacks described above existing for art.
The present invention realizes by the following technical solutions:
A kind of preparation method of 8- aminoquinoline modified starch chelating agent, includes the following steps:
A certain amount of tapioca and sodium metaperiodate are mixed, react under the conditions of being protected from light, make the abundant oxygen of starch by step 1 Change；
Step 2, by the oxidized tapioca that step 1 obtains is washed, alcohol is washed；
Step 3, will through step 2, treated that oxidized tapioca disperses in the right amount of water, a certain amount of 8- ammonia is added Base quinoline, regulation system pH=4-6 react 3-5h, obtain crude product under the conditions of 60-65 DEG C of temperature；
The crude product that step 3 obtains is ground to partial size less than 100 mesh, is washed with volatile organic solvent by step 4, The 8- aminoquinoline modified starch chelating agent is obtained after dried, crushed.
The mass content of each component is as follows as a preferred technical solution:
100 parts of tapioca,
20-50 parts of sodium metaperiodate,
30-75 parts of 8- aminoquinoline.
The reaction time of step 1 is 2-4h as a preferred technical solution,.
As a preferred technical solution, in step 4, volatile organic solvent preferred alcohol, preferably 70% ethyl alcohol is molten Liquid, to remove remaining reactant and further remove moisture.
The partial size of the tapioca is less than 100 mesh as a preferred technical solution,.
The acid is one of hydrochloric acid, acetic acid, phosphoric acid, sulfuric acid as a preferred technical solution,.
The modified starch of the aminoquinoline that the present invention is prepared has good suction-operated to heavy metal ion. Compared with traditional heavy metal processing method, aminoquinoline modified starch has at low cost, less energy consumption, high treating effect, without two The advantages that secondary pollution.
