Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT In this work, In2O3 and three rare earth (RE)‐doped In2O3 composites (Ho, Yb, and Sm‐doped) were prepared via the hydrothermal method. Compared with In2O3 sensors, those fabricated from the three composite materials (RE–In2O3) exhibit varying degrees of enhanced response toward ethylene glycol (EG) gas. At 35% relative humidity (RH) and 250°C,

Gongye shui chuli, 2012 用3种超高交联吸附树脂对4B酸水溶液进行吸附实验,筛选出吸附效果最好的NDA-99树脂。通过静态吸附、动态吸附和脱附实验,探讨了pH、浓度、温度和流速等对树脂吸附4B酸的影响及合适的再生条件。结果表明,该树脂对水溶液中4B酸的吸附主要为物理吸附,降低温度有利于吸附。动态吸附实验表明:在288K下,进液流速为3BV/h的条件下动态饱和吸附量为158.35mg/g;以质量分数为8%的NaOH溶液为脱附剂,脱附流速为1BV/h,脱附温度为343K时,1.5BV的NaOH溶液对饱和树脂的脱附率高达97.5%。
