Description
いくつかの試験を、ほぼ同一の条件下で行った:
樹脂:Lewatit S8227(Lewatitは、Lanxess Deutschland GmbHの商標である)/弱酸カチオン交換樹脂
ダイヤイオン(Diaion)CR11(ダイヤイオン(Diaion)は、三菱化学株式会社の商標である)/弱酸カチオン交換樹脂
充填流体:50〜66gのNi/lのNi溶液(pH4〜4.6)
充填流体流れ:充填のために10BV/時で9BV(最大充填の場合は過剰)(BV:床体積:容器中に充填された後、すなわち、再生後の樹脂材料の体積;BV/時:床体積についての流量)
再生流体:1〜3モル/lの硫酸
温度:室温
1)酸処理:3BV/時で2BV
2)すすぎ:10BV/時で20BV
3)5%のNaOHによる状態調整(Conditioning):10BV/時で6BV
4)すすぎ:10BV/時で10BV
5)充填:10BV/時で10BV
6)すすぎ:10BV/時で10BV
7)再生:1BV/時で2.4〜5.2BV
8)すすぎ:10BV/時で6〜11BV
1)樹脂のタイプ
樹脂のタイプに応じて、貯蔵容量および再生流体中の得られる濃度の大きな差がある。Lewatit S8227は、三菱ダイヤイオン(Diaion)CR11という樹脂と比較してはるかに高い容量を有する。
試験を、3モル/lの硫酸を用いて行った。
収着床の固定が、再生方法の効率に大きな影響を与えることが分かっている。図7は、再生剤流体のための2つの異なる流れ方向における同じ試験を示す。カラムのアスペクト比は、40であった。3モル/lの硫酸を再生剤流体として使用した。1を超えるpHを有する収着床を出る全てのニッケル再生画分を収集した。次に、それぞれ上流または下流の流れ方向の後に得られる再生剤流体中のニッケルの濃度を測定した。図7は、1を超えるpHで分離され得るニッケルの部分(右側のグラフ)および平均濃度(左側のグラフ)を示す。累積された再生物(regenerate)のpHは、より高くなるであろう(約2)が、測定しなかった。
重力おもりを用いた場合の固定:68.5%のニッケルが、75.3gのNi/lの平均濃度で回収された;
重力おもりを用いた固定なし:48.4%のニッケルが、24.0gのNiの/lの平均濃度で回収された。
試験を、1、2.5および3モル/lの硫酸を用いて行った。再生剤流体としての高い酸濃度が、高い金属イオン濃度をもたらすが、これは、各モルの硫酸が、1モルのニッケルイオンを放出し、したがって、より高い濃度の硫酸が、より低い濃度を有する硫酸溶液より高い濃度でニッケルを放出するためである。これは、1モルのH2SO4が、収着床から1モル以下のニッケルイオンを取り出すことができるためであり、そのため、理論的には、再生剤流体中で58.7gのNi/lを超えることはない。他方、収着床の固定を含む収着床が含まれたカラムの好ましい設計は、酸の高い利用率を得るのに必要とされる。これは、低過剰の酸のため、ひいては、比較的純粋な再生物のために必要である。実際には、完全に充填された酸/再生物でさえ、わずかに酸性であり、したがって、上記の最高濃度は、再生が局所濃度ピークをもたらす一方で、収着床の内部の遅延効果が生じない限り、わずかに低くなるであろう。再生剤および樹脂中の金属濃度と酸との間の平衡が、常に生じ、この平衡は、平衡定数によって決定される。したがって、酸の接近(access)を回避することはできない。AR=94を有するカラムを用いて、ニッケルイオンの考えられる最高濃度が得られた(図11を参照)。図11は、1モル/lの硫酸を用いた収着床を出る再生剤流体の再生プロファイルのグラフを示す。
2つの試験を、ほぼ同じ条件下で行った(1BV/時で2.5モル/lの硫酸を用いてまたは5BV/時で3モル/lの硫酸を用いて;AR=22)。より低い流量およびより低い酸濃度を用いた試験の品質はより良好であることが分かったが、ほぼ同じ最高濃度が得られた:
67.6%のニッケルが、96.2gのNi/lの平均濃度で回収された;
48.4%のニッケルが、92.6gのNi/lの平均濃度で回収された。
