ajst-3871	Liu, Yanxia	The Study on Kaolin/corn Stalk Composite Adsorbent Materials Prepared by H3PO4 Activation Method	2023	4	.pdf	application/pdf	2352	87	38	Preparation of Composite Materials (1) Material Science H3PO4,KH2PO4,Al203·2Si02·2H20,C16H18N3ClS,Corn straw,Na2HPO4 (2) Preparation of composite adsorption materials by single factor method Dry the corn stalks planted in the right wing front banner of Chahar, Ulanqab City, wash them and put them into an oven to dry them to constant weight, then crush them for standby. 3. Study on Adsorption Performance Take 20mL 7.5mg/L methylene blue solution into iodine measuring flask, weigh 0.1g of composite adsorption material prepared by single factor method, adsorb it in iodine measuring flask for 3h without light, centrifuge, take the upper clear solution and put it into a cuvette, measure its absorbance A at the wavelength of 663nm with T6 visible spectrophotometer, and according to the formula A=0.2285C- 0.0524,Qt=(C0-Ct)V/m(C0:initial concentration of methylene blue solution (mg/L), V: volume of methylene blue solution (L), m: mass of activated carbon (g))	cache/ajst-3871.pdf	txt/ajst-3871.txt
