D－饱和实验设计优化脱氧剂配方 Ⅰ．铁系脱氧剂的研究

The Optimum Chemical Formula for Deoxidizer by Means of the D-saturated design I.Study on Iron Series Deoxidizers

脱氧剂是能够消除包装系统内游离氧的化学物质，它已广泛应用于食品、医药等领域。本文报道了水分依存型铁系脱氧剂研究。通过Ｄ－饱和实验设计筛选出的最优配方是，Ｆｅ∶ＮａＣｌ∶Ｃ∶ＣａＣｌ＿２（Ｗ／Ｗ）＝１∶０．９０６１∶１∶０．２，最大脱氧量为２３４．８４ｍｌ．Ｏ＿２／ｇ．Ｆｅ；建立了氧气测定的气相分析方法；一系列脱氧剂实验表明，环境温度、环境湿度、脱氧剂的使用剂量等对脱氧速度有影响。

By means of the D-saturated design, the optimum chemical formula for iron seriesdeoxidizer has been selected,The optimum formula is Fe:NaCl:C:CaCl2(w/w)=1:0.9061: 1: 0.2 with the maximum deoxidizing amount of 234. 84ml.O2/g. Fe. It is a water dependent type deoxidizer.The deoxidizing amount was analyzed by gas chromatographic method with TCD detector.The environment temperature and humdity and the dosage of deoxidizer are factors which affect the maxi-mum deoxizing amoumt of this deoxidizer.
