| Abstract | 一种用于雌酮污染土壤的原位固定剂及其制备方法和应用，这种修复材料为高温厌氧快速热解制备的纳米铁锰改性荔枝生物炭。该纳米铁锰改性荔枝生物炭由以下方法制备得到：将制备的荔枝生物炭，与0.1mol/L高锰酸钾溶液和0.1mol/L的氯化铁溶液混合，在40℃温度下超声反应2h，然后常温下振荡2h，再次高温厌氧快速热解，得到纳米铁锰改性荔枝生物炭。应用本发明纳米铁锰改性荔枝生物炭掺杂到雌酮污染的土壤中，96h内未在沥出液中检出雌酮。纳米铁锰改性荔枝生物炭可以实现林果业固体废弃物的再利用，并有效的控制畜禽养殖污染土壤的雌酮迁移，能显著降低雌酮污染的风险。 |
| Other Abstract | The invention discloses an in-situ fixative for estrone-contaminated soil, and a preparation method and an application thereof. The above repairing material is nanometer iron-manganese modified litchibiochar prepared by high-temperature anaerobic rapid pyrolysis. The preparation method of the nanometer iron-manganese modified litchi biochar comprises the following steps: mixing the prepared litchi biochar with a 0.1 mol/L potassium permanganate solution and a 0.1 mol/L ferric chloride solution, carrying out an ultrasonic reaction at 40 DEG C for 2 h, oscillating the obtained solution at normal temperature for 2 h, and carrying out high-temperature anaerobic rapid pyrolysis to the obtain the nanometer iron-manganese modified litchi biochar. When the estrone-contaminated soil is doped withthe nanometer iron-manganese modified litchi biochar, estrone is not detected in a leachate within 96 h. The nanometer iron-manganese modified litchi biochar can realize the reuse of solid wastes in the forestry and fruit industry, and effectively control the migration of estrone in soil contaminated due to livestock and poultry breeding and significantly reduce the risk of estrone contamination. |
