• 摘要：本文研究了自制的巯基棉纤维对十六种微量元素的定量吸附条件、吸附速度、吸附量、吸附强弱顺序和解脱条件。讨论了巯基棉纤维的制备、保存、稳定性、再生使用及吸附时共存物的干扰与消除等问题。 实验得知,巯基棉纤维是一种良好的固体吸附剂,它可以定量吸附水溶液中多种微量重金属离子和某些非金属离子,具有富集倍数大、吸附率高、吸附速度快、选择性强、解脱性能好等优点,且制备简单、操作方便、易于推广。

• Abstract：This paper presents the research results of the condition of quantitative adsorption, the adsorptive rate, the adsorptive capacity, and the adsorptive order of 16 kinds of trace elements by sulfhydryl cotton fiber (SCF) prepared by in this laboratory. The condition of desorption was also investigated. Preparation, storage, stability, and regeneration of the sulfhydryl cotton fiber, and the interfering co-existent substances and its elimination were discussed.The experiments indicate that sulfhydryl cotton fiber is a kind of good solid adsorbent, which can quantitatively adsorb a variety of trace heavy metallic and non-metallic ions from water solution, and also possesses the advantage of high adsorption and desorption, high capability of concentration, rapid adsorptive rate, and good selectivity. Moreover its manufacturing procedure is simple, and operation easy to handle.
