在海因法生产甘氨酸的过程中，需要用粉状活性炭对甘氨酸母液脱色精制甘氨酸，经过分析，活性炭所吸附的物质主要是氰化物，氰化物是一种即有剧毒又容易降解的特殊化合物。本文采用三水平四因素实验，通过碘吸附值计算出再生活性炭的性能恢复率、损耗率、综合恢复率等性能指标，探索了影响该废活性炭再生的主次因素和最佳工艺条件。结果表明，活性炭再生的最佳工艺条件为活性炭用量5 g，微波功率640 W，辐照时间7 min，活化剂ZnCl2的浓度为3 mol／L。在该工艺条件下，该废活性炭的综合恢复率为93．52％。
在海因法生產甘氨痠的過程中，需要用粉狀活性炭對甘氨痠母液脫色精製甘氨痠，經過分析，活性炭所吸附的物質主要是氰化物，氰化物是一種即有劇毒又容易降解的特殊化閤物。本文採用三水平四因素實驗，通過碘吸附值計算齣再生活性炭的性能恢複率、損耗率、綜閤恢複率等性能指標，探索瞭影響該廢活性炭再生的主次因素和最佳工藝條件。結果錶明，活性炭再生的最佳工藝條件為活性炭用量5 g，微波功率640 W，輻照時間7 min，活化劑ZnCl2的濃度為3 mol／L。在該工藝條件下，該廢活性炭的綜閤恢複率為93．52％。
재해인법생산감안산적과정중，수요용분상활성탄대감안산모액탈색정제감안산，경과분석，활성탄소흡부적물질주요시청화물，청화물시일충즉유극독우용역강해적특수화합물。본문채용삼수평사인소실험，통과전흡부치계산출재생활성탄적성능회복솔、손모솔、종합회복솔등성능지표，탐색료영향해폐활성탄재생적주차인소화최가공예조건。결과표명，활성탄재생적최가공예조건위활성탄용량5 g，미파공솔640 W，복조시간7 min，활화제ZnCl2적농도위3 mol／L。재해공예조건하，해폐활성탄적종합회복솔위93．52％。
Activated carbon was used to decolor the mother liquor of glycine with Hydantoin Method, through analysis, activated carbon absorb colored material which was cyanide.Cyanide was a kind of special chemical compound which was very toxic and easily degradative.3 level and 4 factors were used.The recovery rate, attrition rate the total recovery rate and other indexes of the activated carbon were calculated by the iodine amount.The primary and secondary factors and the best technological conditions of regenetation of powder activated carbon were discussed.The total recovery rate of regenerated activated carbon could reach 93.52%when microwave power was 640 W, irradiation time was 7 min and density of ZnCl2 was 3 mol/L with 5 g of quantity of activated carbon.
