【摘要】：二氧化氯作為無機(jī)過氧化物是一種強(qiáng)氧化性的消毒劑,目前,應(yīng)用最多的是固載二氧化氯,但研究表明現(xiàn)有的固載二氧化氯有釋放二氧化氯不穩(wěn)定,釋放時(shí)間短、儲存時(shí)間短等問題,給使用者帶來很多麻煩。開發(fā)釋放時(shí)間長的釋放速率穩(wěn)定性好的緩釋型固載二氧化氯產(chǎn)品是有必要的。本論文對緩釋型過氧化物消毒劑的制備工藝進(jìn)行研究,首先確定固載體天然斜發(fā)沸石的改性方法,根據(jù)過渡金屬氧化物活化亞氯酸鈉產(chǎn)生二氧化氯的機(jī)理確定過渡金屬氧化物負(fù)載過程中的最佳工藝,并確定粘合劑、穩(wěn)定劑的種類和用量。最終確定緩釋型過氧化物消毒劑制備方案為:采用1.0 mol/L的鹽酸溶液和1.0 mol/L的氫氧化鈉溶液將天然斜發(fā)沸石進(jìn)行改性,改性后的沸石采用500℃焙燒溫度為最佳焙燒工藝對金屬氧化物進(jìn)行負(fù)載,粘合劑為黃原膠,用量為沸石質(zhì)量的8%;穩(wěn)定劑為硅膠,用量為沸石質(zhì)量的10%。緩釋型過氧化物消毒劑的含量為10.70%,pH值為9.02,到達(dá)穩(wěn)定釋放的時(shí)間為6天,穩(wěn)定期釋放濃度為22 mg/m3左右,緩釋時(shí)間為94天。通過54℃熱加速于烘箱中放置14天,含量下降率為5.13%,下降率小于10%,儲存期可達(dá)1年。同時(shí)考察溫度、相對濕度對緩釋型過氧化物消毒劑釋放速率的影響。緩釋型過氧化物消毒劑具有很好的除甲醛性能和殺菌性能。甲醛的去除率可達(dá)到100%;大腸桿菌和金黃色葡萄球菌殺滅率為99.9%以上,達(dá)到消毒指標(biāo)。
[Abstract]:Chlorine dioxide as an inorganic peroxide is a strong oxidizing disinfectant. At present, it is mostly used to immobilize chlorine dioxide. However, studies show that the existing supported chlorine dioxide has unstable release of chlorine dioxide and short release time. Short storage time and other problems, to the user caused a lot of trouble. It is necessary to develop sustained release chlorine dioxide with long release time and good stability of release rate. In this paper, the preparation technology of sustained-release peroxide disinfectant was studied. Firstly, the modification method of natural clinoptilolite with solid carrier was determined. According to the mechanism of transition metal oxide activating sodium chlorite to produce chlorine dioxide, the optimum process of transition metal oxide loading was determined, and the binder, the type and amount of stabilizer were determined. Finally, the preparation scheme of sustained-release peroxide disinfectant was determined as follows: 1. 0 mol/L hydrochloric acid solution and 1. 0 mol/L sodium hydroxide solution were used to modify natural clinoptilolite. The modified zeolite was roasted at 500 鈩，
