Abstract

Abstract:

A LiCl-composite curdlan ion gel was prepared and used in the study of air-water harvesting. The water vapor adsorption characteristics of composite adsorbents were studied in open environments with different conditions. The effect of the impregnating salt concentration on the composite adsorbent adsorption performance was investigated. According to the target operating conditions, the optimal ratio of the composite adsorbent components was completed. The adsorption kinetics and isotherm characteristics of the optimized ion gels were studied. The results showed that the composite of 15% LiCl solution had the best comprehensive performance. At the conditions of 35℃and 75%RH, the adsorption capacity of the composite adsorbent was as high as 3.30g/g, which was 6.6 times of the traditional silica gel composite sorbent. Meanwhile, the desorption performance was 3 times of the silica composite adsorbent at the condition of 55℃ and 40%RH. In addition, At the condition of 25℃ and 75%RH, the adsorption kinetics rate of the composite gel sorbent K was as high as 3.48×10^-3s^-1. This study of ion-gel composite sorbent can provide a basis for the air-water harvesting technology.

摘要：

制备了一种LiCl复合可得然离子凝胶，并将其首次用于空气取水性能研究。在不同吸附温度、吸附湿度的开式环境中，完成了复合吸附剂的水蒸气吸附特性研究。探究了浸渍盐的质量浓度对复合吸附剂吸附性能的影响。根据目标工况，完成了复合吸附剂组分的优化配比。对优化后的离子凝胶进行了吸附动力学和等温吸附特性研究。结果表明，15% LiCl溶液复合而成的可得然吸附剂综合性能最佳。在35℃&75%RH下，该复合吸附剂的吸附量高达3.30g/g，是传统硅胶复合吸附剂的6.6倍；在55℃&40%RH工况下实现1.66 g/g的水量脱附，是硅胶复合吸附剂的3倍。在25℃&75%RH下，可得然复合凝胶吸附剂的吸附速率K高达3.48×10^-3s^-1；该离子凝胶复合吸附剂的研究，为吸附式空气取水技术提供了基础支持。
