Simultaneous Determination of Heavy Metals Using Array Based Optical Chemical Sensor
A sol-gel optical chemical sensor encapsulated with complexing agents for simultaneous detection of selected heavy metals such as chromium and iron in aqueous media was fabricated. The sensor was prepared by acid catalyzed copolymerization of tetramethoxysilane(TMOS) and starch. 300μL of TMOS and starch mixture was load to the 96 well plate and then the gelation was completed within 2 hours. Th...
متن کاملOptical transparency of mesoporous metals
We examine the optical properties of metals containing a periodic arrangement of nonoverlapping spherical mesopores, empty or filled with a dielectric material. We show that a slab of such a porous metal transmits light over regions of frequency determined by the dielectric constant of the cavities and the fractional volume occupied by them, with an efficiency which is many orders of magnitude ...
متن کاملChemical Stabilization of Heavy Metals
Heavy metals contamination can be found at battery acid recycling sites, electroplating facilities, military installations, firing ranges, brownfields redevelopment sites, and associated with mining activities. The chemical stabilization process uses non-hazardous chemical binders that permanently stabilize heavy metals. The treated soils contain stable metalreagent compounds that eliminate the...
متن کاملSensing of Heavy Metals Using Caenorhabditis elegans DNA Microarray
Previously we reported that the possibility of sensing of chemical substances using gene expression patterns analyzed by DNA microarray using Caenorhabditis elegans (C. elegans) as a sensor (Matsuno et al., 2002, 2006). In this study, we evaluated sensitivity and selectivity of above system using a customized DNA microarray for heavy metal responded genes. The results showed that this system sh...
متن کاملChemical Sensing Using Microbent Optical Fibers
Introduction Microbend loss has always been an undesirable effect causing problems in fiber optic communication links. However, this phenomenon has been exploited profitably in fabricating a variety of fiber optic sensors [1-46] and in other applications such as development of mode strippers and mode scramblers [47], mode filters, phase shifters [48,49], signal processing [50] etc. The sensing ...
