  1. According the key factors we find, we bring forward a new conception : multilevel suppressor and design a new high performance suppressor whose ion - exchange membrane has bigger areas and using three electrodes including one cathode ( anode ) and two anodes ( cathode ), at the same time we fill the suppression compartment with one kind of ion exchange resin which has moderate exchange capacity. according to our experiment ' s results, we find the new type suppressor has quite high working current efficiency and suppressing capacity. in most cases, the suppressor ' s current efficiency is over 90 % ; the suppressor can transform the naoh ( concentration : 200mmol / l, flow rate : i. oml / min, conductance : over 10000 i - i s cm " ) to pure water ( conductance : 8. 9 it s cm in chapter 3, the high performance suppressor is applied in determination some trace - amounts ions in plating solution, sewage. in this chapter, we also have a research on the gradient ion chromatography

    第二章首先以xyz - 1型電化學抑制柱為例,分析了電化學抑制柱的抑制過程得出影響抑制容量的主要因素主要是抑制柱的電流效率和離子交換膜的極限電流密度,因此採用中等交換能力的離子交換樹脂作為抑制室的填料以提高電流效率,在通常情況下電流效率可達到90以上;在選用同種離子交換膜的前提下,可通過增加離子交換膜的有效面積達到提高極限電流的目的從而提高抑制柱的抑制容量,因此提出了多級抑制的概念並據此研製了共電極式高容量電化學抑制柱,該抑制柱最高可將流速為1 . 0ml / min ,濃度為200mmol / l電導率超過10000 s ? cm ~ ( - 1 )氫氧化鈉溶液抑制為電導率低至8 . 9 s ? cm ~ ( - 1 )的純水,並且具有穩定性高、分析結果準確等優點。
  2. Suppressor is the key part for ic instrument, and developing a high performance suppressor for ic instrument is quite important to gradient ion chromatography, to analysis of some ions which have strong affinities with the functional groups located on the surface of the pellicular ion exchange column packing

    抑制柱是離子色譜儀的一個核心部件,研製具有較高抑制容量的抑制柱對于離子色譜法的梯度淋洗、對于在分離柱上保留時間長的離子分析具有重要的意義。
