CAS: 3147-14-6; 3-Hydroxy-4-((2-Hydroxy-5-Methylphenyl)Diazenyl)Naphthalene-1-Sulfonic Acid

该化合物是一种有机化合物,用作pH值指标,在涉及钙和镁离子的乳房中特别有用,其特点是能够根据不同的pH值改变颜色,通常从酸性条件下的红色向碱性环境中的黄色过渡,该化合物是亚索染色族的成员,有助于其富有活力的颜色. 冷却剂在水中溶解,在正常条件下表现出稳定性,适合化学和环境科学的各种分析应用.其分子结构包括一些功能组,便于金属离子捆绑,提高它作为铬剂的效力. 此外,在实验室环境中经常使用冷却剂评估水质,特别是在确定因钙和镁含量而产生的硬度水平方面.安全数据表明,虽然一般认为在受控制的环境中使用它很安全,但应当遵守适当的处理和处置措施,以尽量减少对环境的任何潜在影响.

    标 题 :Synthesis of 3D-porous Sr(II)/Ir(III) layered hydroxide balls composed of hexagonal sheets for water purification
    发明人:ELSAYED Waleed Elsayed Mahmoud; AL-GHAMDI AHMED ABDULLAH SALEM; AL-TURKI YUSUF ABDULAZIZ
    权利人:UNIV KING ABDULAZIZ
    摘要:Three dimensional (3D), porous, Sr(II)/Ir(III) layered double hydroxide materials with a spherical/balls like shape, are composed of nanohexagonal sheets intercalated with 1-(1-hydroxy-4-methyl-2-phenylazo)-2-naphthol-4-sulfonic acid have a number of uses including removing undesirable organic compounds and materials from polluted water. This removal can be accomplished without disturbing the pH of the water, and with high absorption capacity (2000 mg of pollutants/1 mg of LDH). The spherical/ball like materials are easily cleaned and are amenable to being reused several times.

    标题 :Method for determining a concentration of a synthesis component in a radiopharmaceutical sample
    发明人:LEBEDEV ARTEM Y; ELIZAROV ARKADIJ M
    权利人:TRACE ABILITY INC
    摘要:A method for determining a concentration of a synthesis component in a radiopharmaceutical sample comprises providing an indicator, a metal or a metal complex, contacting the radiopharmaceutical sample with the indicator, metal or metal complex for a period of time sufficient to obtain an interaction, measuring an optical characteristic of the interacted components, and determining a concentration of the synthesis component in the radiopharmaceutical sample based on the measured optical characteristic.
