卫生间专用复合型除臭剂的研制

PREPARATION OF SPECIAL COMPOSITE DEODORANT IN TOILETS

本文研究了以硫酸亚铁为主要成分，配以ＮａＨＣＯ３，抗坏血酸和高岭土，组成了卫生间专用复合除臭剂，采用直接除氨法，间接除氨法和人群感觉法等三种实验室评价方法，找出了其较佳配方。ＦｅＳＯ４∶ＮａＨＣＯ３∶抗坏血酸：高岭土（质量比）为３∶１∶１∶３时，直接除氨法、间接除氨法除氨率为４４４７％和７７６２％，人群感觉法脱除巯基乙酸经６０ｈ实验后，恶臭基本消失。同时，初步考察了该配方的除臭剂的再生效果，即该配方的除臭剂经置于浓氨水中１个月后，于１００℃下干燥４８ｈ，再利用间接除氨法测定基除氨率为５８５３％。

Abstract Special composite deodorant in toilets was prepared with mixing ferrous sulfate,sodium bicarbonate,L-ascorbic acid and kaolin.Three laboratory estimating methods of direct deammoniation method ,indirect deammoniation method and people's feeling method were used ,which found better composition of the special composite deodorant in toilets.The results showed that deammoniation rates of direct deammoniation method and indirect deammionation method were 44.47%and 77.62%,respectively ,and the off flavour of mercaptoacetic acid was almost diminished after sixty hours through people's feeling method,when ferrous sulfate:sodium bicarbonate: L-ascorbic acid :kaolin=3:1:1:3(weight ratio),we also studied the regenerative effect of the deodorant.
