The invention discloses a kind of novel absorption material C/Bi with Photon stimulated desorption performance 2 O 2 CO 3 Preparation method, 9g citric acids are dissolved in 30mL distilled water, until completely dissolved by the aqueous citric acid solution of gained be transferred in reactor in 160 180 DEG C react 4 6h obtain the carbon containing aqueous solution；By 2g Bi (NO 3 ) 3 . 5H 2 O is dissolved in the HNO that 40mL molar concentrations are 0.02mol/L 3 In solution, the carbon containing aqueous solution of 1 15mL is added, 0.9g Na are added after magnetic agitation is well mixed 2 CO 3 , ultrasonic 45min, the pH value that mixed solution is adjusted with NaOH solution is 8 8.5, reacts 8 12h in 140 180 DEG C solution is moved in reactor；After reaction terminates, solution naturally cools to room temperature, by gained precipitation and centrifugal separation, washing, dries the novel absorption material C/Bi for being made and having Photon stimulated desorption performance to the dye of positive ion 2 O 2 CO 3 .Raw material used in preparation process of the present invention is cheap and easy to get, green, reaction condition is gentle and suitable large-scale production, is expected to produce good social and economic benefit. |
