(1)式(I)
で表されるキトサン誘導体を含む、金属イオンの吸着剤。
(4)前記(1)又は(2)記載のキトサン誘導体を含む、希土類元素の吸着剤。
(6)インジウム及びガリウムから選ばれる一種以上を含む溶液に前記(1)又は(2)記載の吸着剤を加えて、インジウム及びガリウムから選ばれる一種以上が吸着した吸着剤を得た後、該吸着剤を酸性溶液で処理する、インジウム及びガリウムの回収方法。
キトサン微粒子(OWOC;粒径212〜300μm)8.0g(49.7mmol)をDMSO100cm3に分散させ、攪拌翼を用いて120rpm、60℃で1時間攪拌し、グルタルアルデヒド100cm3を加え、24時間攪拌を行った。ろ過後、洗浄を行い、さらに蒸留水100cm3に分散させ、常温で60分間攪拌した。その後、水素化ホウ素ナトリウム18.8g(497mmol:キトサンの10等量)を粉末のまま1時間以上かけて加え、24時間攪拌させ、2級アミンを有する架橋キトサンを得た。その後、洗浄を行い1Nの塩酸100cm3に分散させ、90℃で1時間攪拌を行った後、フェニルホスフィン酸70.6g(497mmol:キトサンの10等量)を加え、6時間攪拌し、次いでパラホルムアルデヒド14.9g(497mmol:キトサンの10等量)を加え、さらに24時間攪拌した。ろ過後、洗浄を行い50℃乾燥機で1晩乾燥させた。以下に合成スキームを示す。
0.01、0.03、0.05、0.08、0.1、0.3、0.5Nの水酸化ナトリウム水溶液を調製し、各溶液10cm3中にPPACを0.1gずつ入れ、30℃恒温槽を用いて120rpm、24時間振とうした。その後、溶液をろ過し、ろ液を塩酸で中和滴定することにより水酸化ナトリウムの吸着量を求めた。
25mmol/dm3の金属溶液を1mmol/dm3の硝酸アンモニウム溶液で希釈し、1Nの硝酸とアンモニア水で適宜pHを調整した1mmol/dm3の金属溶液15cm3に、吸着剤PPACを0.05g加え、30℃恒温槽を用いて120rpmで24時間振とうした。その後、溶液をろ過し、平衡pHを測定した。原子吸光光度計またはICP発光分析装置を用いて金属イオン濃度の定量を行い、平衡前後の金属イオンの濃度差から吸着量を求めた。
25mmol/dm3の金属溶液(In(III)、Ga(III))を1mol/dm3の硝酸溶液で希釈し、1mmol/dm3の金属溶液を調製した。その溶液15cm3に、吸着剤PPACを0.05g加え、30℃恒温槽を用いて120rpmで0.5時間から24時間振とうを行った。その後、溶液をろ過した。吸着平衡前後の金属イオン濃度を原子吸光光度計を用いて測定した。
サンプル管にPPAC0.05gと各条件に設定した各金属イオン濃度を含む硝酸アンモニウム溶液を15cm3加え、30℃恒温槽を用いて120rpmで24時間振とうを行った。その後、溶液をろ過した。原子吸光光度計を用いて吸着平衡前後の金属イオン濃度を測定した。
25mmol/dm3のIn(III)を1mmol/dm3の硝酸アンモニウム溶液で希釈し、1Nの硝酸とアンモニア水でpHを約2に調整した1mmol/dm3のIn(III)溶液15cm3に、吸着剤PPACを0.05g加え、30℃恒温槽を用いて120rpmで24時間振とうし、平衡させた。ろ過後、回収したPPACに対して15cm3の脱離溶液(0.1mol/dm3から5.0mol/dm3の塩酸、0.1mol/dm3と1.0mol/dm3の酢酸、0.1mol/dm3と1.0mol/dm3のリン酸)を加え、再び恒温槽を用いて24時間振とうした。平衡後の金属イオン濃度及び脱離後の脱離溶液中の金属イオン濃度を、原子吸光光度計を用いて測定した。
25mmol/dm3の金属溶液を0.1Nから1.0Nのシュウ酸で希釈した1mmol/dm3の金属溶液15cm3に、吸着剤PPACを0.05g加え、30℃恒温槽を用いて120rpmで24時間振とうした。その後、溶液をろ過し、平衡pHを測定した。原子吸光光度計またはICP発光分析装置を用いて金属イオン濃度の定量を行い、平衡前後の金属イオンの濃度差から吸着量を求めた。
