植物基除臭剂的配方设计及净化效果的试验研究

目的通过研究植物基除臭剂的配方,探讨其净化效果。方法采用市售植物复配精油为基底,三甘醇为溶剂,加入一定比例的乳化剂、助剂和去离子水配制植物基除臭剂。乳化剂选用比较常见的10种表面活性剂进行冷储和热储对比试验,助剂选用β-环糊精,通过三因素三水平正交试验确定配方中植物精油、乳化剂和助剂含量。通过气相色谱质谱分析除臭剂的活性成分。净化试验采用静态染毒和自动喷雾系统测试除臭剂的净化效果,并和自然沉降、去离子水和3M异味抑制剂效果进行对比。结果植物基除臭剂检出活性有效成分33种,大部分为含氧化合物。精油质量浓度0.6%、β-环糊精质量浓度1.0%,吐温-80质量浓度3.0%为最佳配比,该植物基除臭剂的平均除臭效率高于去离子水和化学除臭剂,10 min后硫化氢和甲硫醇的净化效率达到100%,30 min后氨气净化效率达到95%。结论植物基除臭剂含有反应活性很高的功能团,能与恶臭物质进行各种化学反应,从而达到抑制恶臭气味的目的,该除臭剂对硫化氢和甲硫醇的净化效果强于对氨气的净化效果。

Formulation design and deodorization effect of a plant material-based deodorant

Objective To study and develop the formulation of a plant material-based deodorant,and to evaluate its deodorization effect.Methods This study developed a formulation of plant material-based deodorant,detected the main volatile components of plant essential oil,and tested the removal rate of ammonia,hydrogen sulfide,and methyl mercaptan.Results Within the formulation,33 active components were detected in the plant essential oil,most of which were oxygen-containing compounds.It was found that 6%of plant essential oil,1.0%ofβ-cyclodextrin,and 3.0%of Tween-80 constituted the optimal formulation.The average purification efficiency of the plant material-based deodorant was higher than those of deionized water and chemical deodorant.At 10 minutes after spraying,the efficiency of eliminating hydrogen sulfide and methyl mercaptan of the plant material-based deodorant reached 100%;at 30 minutes after spraying,its efficiency of eliminating ammonia reached 95%.Conclusion The plant material-based deodorant contains some functional groups of high reactive activity,which can react with odorous substances in various chemical ways to inhibit odors.Its effect of eliminating hydrogen sulfide and methyl mercaptan was better than that of eliminating ammonia.
