A bioassay for determination of lipopolysaccharide in environmental samples.
Although the limulus amebocyte lysate (LAL) assay is widely used to determine the concentration of LPS in biological samples, it is known to be susceptible to interference caused by substances of non-bacterial origin. In particular, polysaccharides such as β-glucans and pectic polysaccharides from fungi or plants, respectively, were shown to give higher LPS readings than were actually present i...

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...
15 صفحه اولUltrasound Assisted Emulsification Microextraction as a Simple Preconcentration Method for Determination of Atrazine in Environmental Samples
We represent an environmentally friendly sample of pre-treatment method, ultrasound assisted emulsification microextraction (USAEME) followed by gas chromatography nitrogen phosphorous detector (GC-NPD), to specify atrazine residues in environmental samples. Some parameters affecting the extraction efficiency such as the type and volume of the extraction solvent, emulsification time and additio...
متن کاملA bioassay for the detection of benzimidazoles reveals their presence in a range of environmental samples
Cobamides are a family of enzyme cofactors that include vitamin B12 (cobalamin) and are produced solely by prokaryotes. Structural variability in the lower axial ligand has been observed in cobamides produced by diverse organisms. Of the three classes of lower ligands, the benzimidazoles are uniquely found in cobamides, whereas the purine and phenolic bases have additional biological functions....
متن کاملDetermination of technetium-99 in environmental samples: a review.
Due to the lack of a stable technetium isotope, and the high mobility and long half-life, (99)Tc is considered to be one of the most important radionuclides in safety assessment of environmental radioactivity as well as nuclear waste management. (99)Tc is also an important tracer for oceanographic research due to the high technetium solubility in seawater as TcO(4)(-). A number of analytical me...
