废水中聚丙烯酰胺在Ｈ⁃Ｂｅｔａ分子筛上的吸附特性
吸附 动力学 吸附热力学
2015/9/24
将Ｈ⁃Ｂｅｔａ用于处理含聚丙烯酰胺（ＰＡＭ）的驱油废水，研究了ＰＡＭ在Ｈ⁃Ｂｅｔａ上的吸附动力学和热力学特征，并考察了吸附条件对吸附
效果的影响．结果表明，吸附过程遵循准二级动力学模型；在低ＰＡＭ初始浓度（１００ｍｇ·Ｌ
－１
）时，吸附表观活化能＞４０ｋＪ·ｍｏｌ
－１
，说明Ｈ⁃Ｂｅｔａ对
ＰＡＭ的吸附以化学吸附为主；在高ＰＡＭ初始浓度（２００和...
Field Comparison of Real-Time PM2.5 Readings from a Beta Gauge Monitor and a Light Scattering Method
Beta gauge monitor Light scattering monitor PM2.5 Relative humidity

In this study, PM2.5 mass readings by a portable light scattering monitor (Dust Trak) were
compared to those obtained using a collocated beta gauge monitor (E-BAM) at various ambient
relative humidi...
