1500 MPa级高强度钢42CrMoVNb的氢吸附行为李阳1,张永健1,惠卫军1,王毛球1,董瀚1(1.北京市钢铁研究总院先进钢铁材料技术国家工程研究中心)摘 要:采用阴极充H和H热分析等实验方法,研究了新开发的1500MPa级高强度钢42CrMoVNb在不同奥氏体化温度淬火和不同温度回火后的H吸附行为,并与常用钢42CrMo进行了对比.结果表明,在淬火态及不同温度回火处理后,42CrMoVNb钢充H试样的H逸出曲线峰值温度θP在200-250℃之间.回火温度从200℃升高到......
土上阳离子发生离子交换反应而赋存在矿土上,它能被其他阳离子再次交换解吸,是一种可逆吸附；固定态铵由铵发生专性吸附而赋存在矿土上,离子的专性吸附被认为不由吸附剂带电性决定,不受离子交换影响,通过离子键,共价键或配位键吸附在吸附剂上,一般存在于双电层的内层[9-10],是一种不可逆吸附. 根据Dual- Equilibrium Desorption(DED)模型[11]的描述,吸附质在吸附剂上吸附和解...

of the raffinate solution flow. Using sodium carbonate for elution, desorption of Sc, Y and Ce from the resin during static elution tests at constant duration was higher than that of Fe, Al and Cu. The results from the dynamic tests followed similar trends for the priority and the extent of the elution process. Desorption results from specimens of dynamic tests show a 60:1 concentration ratio leading......
to improve the moisture absorption and desorption performance, and then kinetic experiments of moisture absorption/release on the humidity-controlling composite materials were carried out with the help of batch adsorption/desorption experiment. The thermal decomposition temperature and structure of humidity-controlling composite material were estimated separately by means of TG-DTA and FTIR......
