The specific embodiment
Get respectively 5ml butyl titanate and 20ml absolute ethyl alcohol, the adding mass concentration is 37% concentrated hydrochloric acid 0.5ml, mix, the halogen worm's ovum shell that adds the cleaned oven dry of 0.2g is with its ultrasonic (supersonic frequency 40KHz, ultrasonic power 50W, temperature is 50 ℃) disperseed 2 hours, filter, with the absolute ethyl alcohol flushing for several times, it is in the 5%NaOH solution that the halogen worm's ovum shell that has been written into butyl titanate is added mass concentration, fully stir, make the butyl titanate complete hydrolysis in the halogen worm's ovum shell, filter, with deionized water rinsing for several times, in 80 ℃ drying box, dry, then with its charing, again roasting 2 hours under 500 ℃ of high temperature in Muffle furnace makes halogen worm's ovum shell and carries TiO
2Biocomposite material (such as Fig. 1).
Halogen worm's ovum shell carried titanium dioxide composite of the present invention can be used for Degradation Formaldehyde.In order to verify the effect of Biocomposite material degradation of formaldehyde among the present invention, design and implemented the control experiment of halogen worm's ovum shell carried titanium dioxide composite degradation formaldehyde under illumination and the lucifuge condition.
Getting respectively mass concentration is that 36% each 0.5ml of formaldehyde standard liquid joins in 2 tubualted bottles, and bottleneck is sealed with preservative film, with sealing strip it is obturaged, and is placed in the incubator, and lucifuge treats that its volatilization is evenly distributed; The TiO that respectively 0.25g is prepared
2-halogen worm's ovum shell composite is evenly coated on 2 hardboards that are stained with double faced adhesive tape; One of them tubualted bottle is put with shade bag, make its lucifuge, another keeps intact it; Scribble TiO with 2
2The hardboard of-halogen worm's ovum shell is put into respectively the bottle that is full of formaldehyde gas, clogs bottleneck with rubber stopper, with sealing strip bottleneck is obturaged; Respectively it is carried out sample detecting with air sampler, afterwards every one hour once sampling, each flow 0.2L/min gathers 1.5min, adopts the phenol reagent AAS to measure gathering the gas sample.Degradation results is as shown in table 1.
The comparative test result of the halogen worm's ovum shell degradation of formaldehyde of carried titanium dioxide shows under lucifuge and the illumination, halogen worm's ovum shell carried titanium dioxide composite PARA FORMALDEHYDE PRILLS(91,95) under illumination condition has preferably degradation effect, and its under illumination condition than lucifuge condition under good degrading effect, this is because illumination can excite the photocatalytic Degradation of halogen worm's ovum shell carried titanium dioxide composite, and the minimizing of content of formaldehyde during lucifuge mainly is because the suction-operated of halogen worm's ovum shell carried titanium dioxide composite produces.This is because carrier halogen worm's ovum shell of the present invention has loose structure, can successful carried titanium dioxide, and halogen worm's ovum shell and titanium dioxide can play mutually collaborative effect in the process of degradation of formaldehyde.
