ساخت الکترودهاِی اصلاح شده ِیکِی از چالشهاِی همِیشگِی در دانش شیمِی بوِیژه شیمِی تجزیه مِی باشد ،که با در نظر گرفتن سادگِی ساخت، کاربردی بودن و ارزان بودن روش مِی توان به باارزش بودن چنِین سنسورهاِی پِی برد.آنچه که در ادامه آورده شده به ساخت و کاربرد الکترودهاِی اصلاح شده با استفاده از نانو ذرات در اندازه گِیرِی ولتامترِی آهن وکادمِیم اشاره دارد. کار اول اختصاص دارد به ساخت الکترود خمِیر کربن اصلاح شده با لِیگاند داِ...

An improved procedure for the determination of carbon in organic compounds in aqueous solution.

The rapid semi-micro determination of carbon by wet combustion of organic compounds (Van Slyke & Folch, 1940) has been subjected to various modifications, principally in the apparatus used (McCready & Hassid, 1942; Hockenhull, 1950). The apparatus is shown in Fig. 1, and is essentially that described by Hockenhull (1946; and personal communication), using the spiral bubbler modified from that o...

Aqueous Solution Surface Chemistry of Carbon Nanotubes

Direct determination of carbon dioxide in aqueous solution using mid-infrared quantum cascade lasers.

A method for the direct determination of carbon dioxide in aqueous solutions using a room-temperature mid-infrared (MIR) quantum cascade laser at 2330 cm(-1) is reported. The absorption values of different carbon dioxide concentrations were measured in a 119 microm CaF2 flow-through cell. An optical system made of parabolic mirrors was used to probe the flow cell and to focus the laser beam on ...

The solubility values determined by voltammetry have been overestimated because of adsorption on electrodes...
