摘要

本研究观察了EDTA和H2C2O4在283、293和303 K下的吸附情况。采用美国Zeolyst International公司生产的合成沸石NH4BETA为吸附剂,SiO2/Al2O3的摩尔比为25.00,考察其物理化学特性,更全面地了解其吸附能力和活性中心,并探讨其在有机污染物废水净化中的潜在应用。结果证明,在相同的实验条件下,吸附剂的吸附是多层物理的,当吸附剂为草酸时,吸附剂的吸附表现更强,这是合乎逻辑的,因为它的分子比EDTA的大分子小得多,结构更简单。

Study of adsorption of selected organic species from aqueous solution on nh4be ta zeolite
This study observed adsorption of selected organic species from the aqueoussolution, EDTA and H2C2O4, at 283, 293 and 303 K. The adsorbent used was syntheticzeolite NH4BETA, product of the American company Zeolyst International, with themole ratio of SiO2/Al2O3 = 25.00, for the purpose of examining its physical-chemicalcharacteristics and obtaining more thorough information on the adsorption capacityand active centers, as well as for its potential application in purificati on of wastewatersfrom the organic pollutants. Results proved that adsorption of the adsorbates, underthe same experimental conditions, was multi-layer physical, being stronger expressedwhen the adsorbate was oxalic acid, which is logical enough since its molecule is a lotsmaller and of a simpler structure compared to the big molecule of EDTA.
