heavy metal concentrationとは 意味・読み方・使い方

Heavy metals contained in the carbonized product 4 are eluted into the water by the washing, to decrease a heavy metal concentration in the carbonized product 4.例文帳に追加

この洗浄により炭化物４に含有されている重金属を水に溶出させて、炭化物４の重金属濃度を低減させる。 - 特許庁

When the end point of such the formation reaction that the heavy metal is precipitated as its sulfide by using a sulfurizing agent to the extent of the objective concentration of the heavy metal is judged, the ORP is measured and simultaneously the concentration of hydrogen sulfide (H_2S) gas in the upper part of a reaction tank is measured.例文帳に追加

硫化剤を使用して重金属を目標濃度まで沈殿させる反応の終点を判定する際に、ＯＲＰの測定と同時に、反応槽上部の硫化水素（Ｈ_２Ｓ）ガス濃度を測定する。 - 特許庁

To reduce the contamination of incineration residue and contaminated soil with heavy metals by efficiently extracting and separating the heavy metals by a convenient method from the heavy metal-containing waste such as the incineration residue and the contaminated soil containing heavy metals in a high concentration and lowering the heavy-metal content of the extracted residue and to accurately measure the elution of the heavy metals from such waste by a convenient method.例文帳に追加

重金属を高濃度で含有する焼却残渣や汚染土壌などの重金属含有廃棄物から、簡易な方法で重金属を効率的に抽出分離し、抽出残渣の重金属含有値を下げることにより、焼却残渣や汚染土壌の重金属汚染を軽減する。 - 特許庁

To provide an automatic measuring device of heavy metal concentration capable of preventing scattering of hazardous materials in ash.例文帳に追加

灰中の有害物質が飛散するのを防止し得る重金属濃度の自動計測装置を提供する。 - 特許庁

The alkali metal halide is prepared in an aqueous solution of the concentration of 0.5-1.5 mol/L, which is used at a weight ratio of 5-10 times as much as the heavy metal- contaminated soil.例文帳に追加

アルカリ金属ハロゲン化物は、濃度０．５〜１．５モル／リットルの水溶液とし、重金属汚染土壌に対して重量比で５〜１０倍使用する。 - 特許庁

To effectively recover valuable metal with high concentration in burning raw material of low quality such as heavy oil and petrokokes containing plenty of metal.例文帳に追加

金属を多く含む重質油、ペトロコークス等の低品位の原料を燃焼設備で燃焼する際に、有価金属を高い濃度で効果的に回収する。 - 特許庁

The concentration of the alkali earth metal ion and the heavy metal ion is preferable to be within a range of 0.01 mol/dm3 or more but 0.1 mol/dm3 or less as the total.例文帳に追加

アルカリ土類金属イオンおよび重金属イオンの濃度は、それらの合計で０．０１ｍｏｌ／ｄｍ^3 以上０．１ｍｏｌ／ｄｍ^3 以下の範囲内が好ましい。 - 特許庁

To provide a method for removing heavy metal ions in wastewater by which the heavy metal ions in the wastewater can be removed to sufficiently low concentration satisfying an environmental standard and which is simple and has high treatment efficiency.例文帳に追加

環境基準を満たす、十分低い濃度まで、排水中の重金属イオンを除去することができ、かつ、簡易で、処理効率のよい、排水中の重金属イオンの除去方法を提供すること。 - 特許庁
