Description
ム(IV)であってよい。亜ヒ酸塩およびヒ酸塩は、百万分率(ppm)または十億分率(ppb)もしくは1ppbの数分の1の濃度で存在し得る。セリウム含有組成物は、高処理濃度または超低処理濃度で、水性液体流から亜ヒ酸塩およびヒ酸塩を除去できる。

は、約pH7で約30mV以下かつ約1mV超のゼータ電位を有する;(ii)酸化セリウム(IV)組成物は、約0.5μm超かつ約20μm以下の粒径D10を有する;(iii)酸化セリウム(IV)組成物は、約2μm超かつ約20μm以下の粒径D50を有する;(iv)酸化セリウム(IV)組成物は、約12μm超かつ約50μm以下の粒径D90を有する;(v)酸化セリウム(IV)組成物は、約1nm超かつ約22nm以下の微結晶サイズを有する;および(vi)酸化セリウム(IV)組成物は、約0.0001酸点/kg超かつ約0.020酸点/kg以下の酸点濃度を有する、ことのうちの1つ以上が当てはまる。
一部の実施形態では、酸化セリウム(IV)組成物は、ヒ素含有流中の1μg/Lのヒ素(III)当たり1gのCeO2当たり、セリウム(IV)酸化物(セリウム(IV)の酸化物)より約125%多いヒ素(III)を除去し、かつ工程(i)〜(vi)のうちの1つ以上は該セリウム(IV)酸化物に対して当てはまらない。
ヒ酸塩負荷能力を有する先行技術のセリウム(IV)酸化物についてのヒ酸塩に対する負荷能力とは対照的である。
)〜(ii)および(iv)〜(vi)のうちの4つは当てはまらず、かつ工程(i)〜(ii)および(iv)〜(vi)のうちの他の工程は当てはまり得る。
一部の実施形態では、粒径D10は、約1〜約3μmであってよい。
一部の実施形態では、粒径D90は、約20〜約30μmであってよい。
一部の実施形態では、微結晶サイズは、約7.5〜約12.5nmであってよい。
一部の実施形態では、酸化セリウム(IV)組成物は、Ce(IV)O2以外の希土類酸化物を有していてよい。酸化セリウム(IV)組成物は、酸化セリウム(IV)以外の該希土類酸化物を、約40重量%以下、約25重量%以下および約10重量%以下のうちの1つで有していてよい。
本明細書で使用する「少なくとも1つ」、「1つ以上」および「および/または」は、用法が接続的および離接的の両方である限定のない表現である。例えば、「A、BおよびCのうちの少なくとも1つ」、「A、BまたはCのうちの少なくとも1つ」、「A、BおよびCのうちの1つ以上」、「A、BまたはCのうちの1つ以上」ならびに「A、Bおよび/またはC」との表現の各々は、Aのみ、Bのみ、Cのみ、AおよびBを一緒に、AおよびCを一緒に、BおよびCを一緒に、またはA、BおよびCを一緒を意味する。上記の表現中のA、BおよびCの各1つが例えばX、YおよびZなどの1つの要素または例えばX1〜Xn、Y1〜YmおよびZ1〜Zoなどの要素の群を意味する場合、この語句は、X、YおよびZから選択される単一要素、同一群から選択される要素の組み合わせ(例えば、X1およびX2)ならびに2つ以上の群から選択される要素の組み合わせ(例えば、Y1およびZo)を意味することが意図されている。
本開示を通して与えられるあらゆる最高数値限定は、それより低いあらゆる数値限定を、そのようなより低い数値限定が本明細書に明示的に記載されているかのように、代替として含むと見なされる。本開示を通して与えられるあらゆる最低数値限定はそれより高いあらゆる数値限定を、そのようなより高い数値限定が本明細書に明示的に記載されているかのように代替として含むと見なされる。本開示を通して与えられるあらゆる数値範囲は、そのようなより広い数値範囲内に含まれるそれより狭いあらゆる数値範囲を、そのようなより狭い数値範囲が本明細書に明示的に記載されているかのように含むと見なされる。例えば、約2〜約4の語句は、約2〜約3、約3〜約4からの全ての数および/または整数範囲ならびに実数(例えば、無理数および/または有理数)に基づく可能性のある各範囲、例えば約2.1〜約4.9、約2.1〜約3.4などを含む。
れるであろうように、本開示の他の態様、実施形態および形態は、上記に規定した、または以下で詳細に記載する特徴の1つ以上を単独または組み合わせて利用することが可能である。同様に、本開示は典型的な実施形態に関して提示したが、本開示の個々の態様は別個に特許請求できると理解されたい。
れている。水性液体流は、望ましくない量のヒ素を含有する飲料水および地下水のうちの1つ以上であってよい。さらに、水性液体流は、限定なく井戸水、地表水(例えば湖、沼および湿地帯からの水)、農業用水、工業プロセスからの廃水および地熱水を含むことができる。
り一般的には約3μm以下の粒径D10を有する。粒径D10は、典型的には約1〜約3μmの範囲に及ぶ。何らかの理論によって拘束されることは望まないが、酸化セリウム(IV)組成物の粒径D10は、水性液体流からのヒ素の除去に影響を及ぼし得ると考えられる。酸化セリウム(IV)組成物が上記のゼータ電位、等電点、表面積、平均細孔容積および平均孔径ならびに下記の微結晶サイズおよび酸点数のうちのいずれか1つ以上と組み合わせた上記のD10粒径のうちのいずれか1つを有し得ることは理解できる。
は様々であり得る。酸化セリウム(IV)組成物は、典型的には約75重量%超のCe(IV)O2、より典型的には約85重量%超のCe(IV)O2、いっそうより典型的には約90重量%超のCe(IV)O2、またはさらにいっそうより典型的には約99.5重量%超のCe(IV)O2を含んでいる。
5%、および99.9%超を除去することを意味する。
下記の実施例は、本開示の所定の態様、実施形態および形態を例示するために提供するが、添付の特許請求の範囲に規定した本開示の限定として見なすべきではない。全ての部および割合は、他に特に規定しない限り重量による。
酸化セリウム(IV)組成物を下記の方法によって調製した。密閉された撹拌容器内で、1Lの0.12M硝酸セリウム(IV)アンモニウム溶液を、硝酸中に溶解させた硝酸セリウム(IV)アンモニウム結晶から調製し、約24時間にわたりおよそ90℃で保持した。別個の容器内で200mLの3M水酸化アンモニウム溶液を調製し、室温で保持した。引き続いてこれら2種の溶液を混合し、およそ1時間撹拌した。生じた沈降液を、ろ紙を装備したビュックナー(Buecker)漏斗を使用してろ過した。次に固体を脱イオン水を用いてビュックナー漏斗内で完全に洗浄した。洗浄/濾過工程後に、湿性水和物を3時間にわたりおよそ450℃のマッフル炉内で焼成して、酸化セリウム(IV)組成物を形成した。
ヒ素(V)を含有する試験溶液を、NSF/ANSI53「飲料水処理ユニット−健康への影響」規格文献のセクション7.4.1.1.3に規定されたNSF53ヒ素除去水についての指針にしたがって調製した。20mgの市販で入手できるセリウム(IV)酸化物(Ce2(CO3)3・6H2Oを焼成することにより調製されるとともにpH7で約16mVのゼータ電位、約pH8.8の等電点、約4μmの粒径D10、約30μmの粒径D50、約90μmの粒径D90、および約19nmの微結晶サイズを有するCeO2。マッフル炉内で2時間)を、500mL密閉ポリエチレン製容器内に入れ、表1〜8に記載した濃度で約500mLのヒ素試験溶液を用いてスラリー化した。生じたスラリーを、数時間にわたり容器を回転させることにより撹拌した。撹拌後、試験溶液を、0.45μm(ミクロン)のシリンジフィルタを通じたろ過により固体から分離した。ろ液を、125mLプラスチック製サンプルボトル内に密閉して認定飲料水分析研究所に送付し、そこで、各ろ液中のヒ素の量がICP質量分析法により決定された。これらの試験の結果は、以下の表9〜16に表示される。
セリウム(IV)組成物は、各初期濃度水準でより多くのヒ素を除去するだけではなく、その除去能力はまた、初期ヒ素濃度の増加に伴い先行技術のセリウム(IV)酸化物に比してより緩徐に低下する。これは、図1および2の線の各々の傾斜によって示されている。
を各初期ヒ素濃度水準で除去するとともに、そのヒ素(III)および(V)の除去能力は初期ヒ素濃度の増加に伴い、より緩徐な速度で低下する。
いて、pHに応じたヒ素(III)および(V)除去において向上した結果を示すという事実にもかかわらない。
様々な態様、実施形態および構成における本開示には、様々な態様、実施形態、形態、部分組み合わせならびにそれらの小集団を含む、本明細書に実質的に描出および記載した成分、方法、工程、システムおよび/または機器が含まれる。当業者であれば、本開示を理解した後は、様々な態様、態様、実施形態および形態を作成および使用する方法を理解できるであろう。様々な態様、実施形態および形態における本開示は、例えば性能を改良する、実施の容易さを達成する、および/または費用を減少させるために、上記の装置または方法において使用されていた可能性のあるそのような品目の非存在下を含む本明細書に描出および/または記載していない品目の非存在下において、装置および方法を提供する工程を提供することを含む。
および修飾形態の説明を含めているが、他の変形形態、組み合わせおよび修飾形態は、例えば本開示を理解した後には、当業者の技術および知識の範囲に含まれるように、本開示の範囲内に含まれる。許容される程度まで代替的な、互換可能な、および/または特許請求されるものに対して均等な構造、機能、範囲または工程を含む代替の態様、実施形態および形態を含む権利を得ることが、そのような代替的な、互換可能な、および/または均等な構造、機能、範囲または工程が本明細書に開示されるかどうかには関わらず、および任意の特許可能な主題に公的に専心することは意図せずに、意図されている。
