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...

The Determination of Trace Mercury in Environmental Samples: A Review

Mercury has long been recognised as a neurotoxin element for many decades and with its compounds being extremely toxic, is ranked third in the ‘priority list of hazardous substance’ by the United States comprehensive environmental response, compensation, and liability act. In different samples, mercury can exist as either its inorganic or organic forms and this paper will review the methods for...

Automatic determination of mercury in samples of environmental interest

Bead-injection determination of total mercury in river water samples.

A bead-injection system is proposed for total mercury determination in river-water samples. The procedure is based on the introduction of a defined quantity of a resin suspension in the flow system. The selected beads are packed inside of a flow cell and the formed resin mini-column constitutes the optical path. The sample volume is then selected, and its passage by the mini-column allows reten...
