Description
Technical field
The invention belongs to the hydrotalcite technical field, be specifically related to the application of Mg-Al hydrotalcite tetracycline in removing water.
Background technology
(tetracycline is a kind of typical bactericidal properties medicine TET) to tsiklomitsin, is Broad spectrum antibiotics, belongs to recalcitrant substance.Contain certain density tsiklomitsin and corresponding poisonous derivative in the trade effluent of pharmaceutical factory's discharging of many production tsiklomitsins, it is directly entered in a large number can cause biological mass mortality in the water body in the natural water, destroy the eubiosis of water body.When the pH of solution value changed, the exist form of tsiklomitsin in the aqueous solution also changed thereupon.Along with pH from low to high, present+1,0 ,-1-2 equivalent states respectively.
The domestic and international at present treatment process for the tsiklomitsin in the water mainly contains aerobe processing, anaerobic biological treatment and charcoal absorption etc.Studies show that all there is certain limitation in above-mentioned treatment process, be subject to the inhibition of tetracyclines antibiotic as biological treatment, and the active carbon adsorption adsorption efficiency is lower, and sorbent material reclaims, the regeneration difficulty, the processing cost height.Therefore the tetracyclines pollutent of seeking in a kind of efficient feasible method treating water is very necessary.
Adsorption is meant that one or more material molecules are attached to the lip-deep process of another kind of material (generally being solid).Absorption is surface phenomenon, is to be adsorbed dense gather of molecule on the interface.Usually people call sorbent material to sizable materials of specific surface area such as gac, silica gel, molecular sieve, polymeric adsorbents, and the material adsorbed sorbent material calls adsorbate.In recent years, scholars generally believe the sorbent material that utilizes high-specific surface area, remove hazardous and noxious substances in the water by adsorption, are one of effective meanss of water pollution control.
(hydrotalcite HT) is a kind of anionic clay with laminate structure to hydrotalcite-based compound.In hydrotalcite compound, because trivalent metal ion has partly replaced divalent-metal ion, make the basic structure layer show positive polarity, compensate negative charge so can fill negatively charged ion between laminate and laminate.The interlayer anion of hydrotalcite-based compound has certain transport property and very strong interchangeability, promptly is in the CO between the structural sheet
3 2-, NO
3 -, SO
4 2-, Cl
-Can be replaced by other negatively charged ion in the environment Deng negatively charged ion.With CO
3 2-, NO
3 -Plasma is the hydrotalcite-based compound of interlayer anion, and after roasting, negatively charged ion can decompose between laminate, and simultaneously, its laminate structure is collapsed, and the sosoloid of formation bimetallic oxide (calcinedhydrotalcite, C-HT).In the aqueous solution, the bimetallic oxide compounds can recover the stratiform double electrical layers of hydrotalcite, i.e. " memory effect " of hydrotalcite by the negatively charged ion in the absorption environment.Therefore can utilize hydrotalcite-based compound, the tsiklomitsin in the water is removed in the bimetallic oxide compounds absorption that particularly obtains after its roasting.At present existing with Mg-Al type hydrotalcite be applied to print and dye, the research report of aspects such as papermaking, plating and nuclear industry wastewater treatment.Yet the method for utilizing Mg-Al type hydrotalcite to remove the tsiklomitsin in the water still is not reported.
Summary of the invention
The objective of the invention is self-characteristic, the application of a kind of Mg-Al hydrotalcite tetracycline in removing water is provided at Mg-Al type hydrotalcite.
Another object of the present invention provides a kind of method of removing tsiklomitsin pollutent in the water with the Mg-Al hydrotalcite.
Purpose of the present invention can reach by following measure:
The application of Mg-Al hydrotalcite tetracycline in removing water.
A kind of Mg-Al hydrotalcite is removed the method for tsiklomitsin in the water, be that 4～2: 1 Mg-Al hydrotalcite (preferred pH 5～8) under acidity or meta-alkalescence condition adsorbs removal to the tsiklomitsin in the water with baked Mg/Al mol ratio, adsorption time is 5min～24h, and temperature is 298～308K.The starting point concentration of tsiklomitsin pollutent is 10～230mg/L in the water.The consumption of sorbent material can be regulated as the case may be, and preferred adsorbent and micro-polluted water mass ratio are 1: 400～600.
The present invention is a sorbent material with the Mg-Al hydrotalcite, and the tsiklomitsin pollutent in the water is removed in absorption.The Mg-Al hydrotalcite is carried out roasting can improve its absorption property, its adsorption effect to tsiklomitsin in the water is significantly improved.
Calcined hydrotalcite does not mainly show as ion exchange to the absorption of tsiklomitsin, and is not good to the adsorption efficiency of tsiklomitsin.CO
3 2-Be interlayer anion very stable in the hydrotalcite-based compound, other negatively charged ion is difficult to its interlayer from hydrotalcite is cemented out, and causes that calcined hydrotalcite is unlimited to the adsorptive capacity of tsiklomitsin.Hydrotalcite can recover its original laminate structure by absorption tsiklomitsin negatively charged ion after the roasting.After the roasting hydrotalcite to the adsorptive capacity of tsiklomitsin much larger than calcined hydrotalcite not to the adsorptive capacity of tsiklomitsin.
Method with tsiklomitsin in the Mg-Al hydrotalcite removal water specifically may further comprise the steps:
1, adopts the synthetic Mg-Al type hydrotalcite of hydrothermal synthesis method;
2, roasting Mg-Al type hydrotalcite 4h;
3, be sorbent material with the Mg-Al type hydrotalcite of not roasting and the Mg-Al type hydrotalcite after the roasting, the tsiklomitsin in the water is adsorbed, but the time-temperature root a tree name actual conditions of absorption is done suitably adjustment, the preferred time is 5min～24h, and temperature is 298～308K.
