摘要
(CN106995224) 本​发明​公开​了​种​去除​水中​抗生素​的​方法,包括:1)收集​的​甘蔗​皮,预处理​后​放入​管​式​炭化​炉​烧制​处理,制备​出​甘蔗​活性炭;2)取​甘蔗​活性炭,加入​改性​剂​进行​改性​处理;3)改性​后的​甘蔗​活性炭​去除​水中​的​抗生素。本​发明​生物质​炭​产​率​约为​31%,30%过氧化氢​超声​浸渍​改性​产​率​约为​89%,生产​出来​的​生物质​炭​可​高效​吸附​水中​磺胺类​抗生素,在​pH=4、35℃的​吸附​条件下,对​甲​恶​唑、噻唑、甲基​嘧啶​以及​二甲​基​嘧啶​等​磺胺类​抗生素​具有​较好​的​吸附​能力,尤其是​500℃烧制​并经​30%过氧化氢​改性​及​超声​浸渍​改性​后生​物​炭​去除​效果​最佳,用​甘蔗渣​为​原材料​制备​生物质​炭​是​种​资源​再利用​的​良好​途径,除​可​吸附​水中​抗生素​外,在​其他​污染物​去除​方面​定​也有​很好​的​应用​前景。

(CN106995224) 1. One method of antibiotics removing water, characterized in, comprises the following steps: 1) collection of the sugarcane rind, pre-baking treatment after the carbonization furnace tube was placed, to prepare a sugar cane activated carbon; 2) taking sugar cane activated carbon, the modifier is added for modification; 3) removing the water of the activated carbon modified sugar cane antibiotic. 2. Removing water borne antibiotic method according to claim 1, characterized in, step 1) was, then rinsed with tap water will be collected sugarcane rind, air-dried for 2 days, 12 hours and then placed into an oven 70 °C drying, re-using a grinder to a particle size not more than 2 cm; a weighed sugarcane rind fines with a foil paper good in a porcelain crucible, covers the cap to pass into tube carbonization, raised at a rate of temperature increase of 10 °C/min to 500 °C target temperature, held 2 hours, allowed to cool to room temperature the product was ground through the 50 mesh sieve; subsequently, 1200 ml 1 mol/L hydrochloric acid for 2 hours to remove calcium carbonate and the like with ash material, multi-purpose vacuum pump was suction-filtered with circulating water, and washed with deionized water after washing was neutral, placed in 24 hours was oven 80 °C, into the sample save bottles stored for further use. 3. Removing water borne antibiotic method according to claim 1, characterized in, step 2) was, 11.25 g of the 1000 ml beaker was put into bio-char after washing, a modifier is added to the beaker and a sufficient contact respectively, modifying treatment was followed by repeatedly washed until neutral, and then placed in an oven to constant weight drying oven 60 °C 12 hours. 4. Removing water borne antibiotic method according to claim 1, characterized in, step 3) was, bio-charcoal in 50 ml of a 0.5 g is weighed colorimetric tubes, adding 10 ml of the mixed liquor sulfa antibiotics concentrations of 20 mg/L, pH adjusted to 4, at a constant temperature shaking at 35 °C 24h, four sulfa antibiotics adsorption and desorption on the mixture. 5. Removing water borne antibiotic method according to claim 1, characterized in, step 1) was, at 300 - 700 °C activated charcoal fired at a temperature out of the cane. 6. Removing water borne antibiotic method according to claim 1, characterized in, step 2) was, modifier is selected from concentrated sulfuric acid, concentrated nitric acid, 0.4 mol/L potassium permanganate solution or hydrogen peroxide 30%. 7. Removing water borne antibiotic method according to claim 1, characterized in, step 2) are, respectively is modified by a dipping and ultrasonic dipping method. 8. Removing water borne antibiotic method according to claim 7, characterized in, dipping-modified: 1000 ml beaker 11.25g after washing of the bio-char will be put, 400 ml beaker were added and to intimate contact between the oxidizing agent and activated carbon, solids were removed after 24 hours and was repeatedly washed until neutral, and then placed in an oven to constant weight drying oven 60 °C 12 hours. 9. Removing water borne antibiotic method according to claim 7, characterized in, ultrasonic immersion modified: 1000 ml beaker was washed 11.25g into bio-char, and activated carbon was added 400 ml beaker and provides intimate contact between the oxidizing agent respectively, 10 minutes after ultrasound, stand for an additional 24 hours and was repeatedly washed until neutral solid was removed, and then placed in an oven to constant weight drying oven 60 °C 12 hours. 10. Removing water borne antibiotic method according to claim 1 or 4, characterized in, antibiotics include methyl oxazole, thiazole, mthylpyrimidin and dimethyl pyrimidine.
