Fresh water source scarcity in arid and semiarid area is limitation factor for saline-sodic soil reclamation. The reusing of agricultural drainage and industrial wastewater are preferred strategies for combating with this concern. The objective of current study was evaluation in application of industrial sugar manufacture wastewater due to high soluble organic compounds in saline-sodic and sodi...

background: toluene is a volatile organic compound, one of 189 hazardous air pollutants (hap s ) and the most important pollutant found in most industries and indoor environments; owing to its adverse health, toluene must be treated before being released into the environment. methods : in this research study, a continuous-flow system (including an air compressor, silica gel filters and activate...

background: volatile organic compounds (vocs) are human-made chemicals widely spread in the environment and produced by petrochemical industries and petroleum refineries. the aim of this research was to evaluate the distribution of vocs in the ambient air of mahshahr petrochemical complex, iran. methods: this study was a cross-sectional research performed in 2009. we used the method numbered 15...

After exposing intact chloroplasts isolated from spinach (Spinacia oleracea L. cv Yates) and capable of photoreducing CO(2) at high rates to different concentrations of radioactive sulfite in the light or in the dark, (35)SO(2) and H(2) (35)S were removed from the acidified suspensions in a stream of nitrogen. Remaining activity could be fractionated into sulfate, organic sulfides, and sulfite ...

a new method for analysis of benzene, toluene, and xylene (btx) using high performance liquid chromatography-uv detection (hplc-uv) is described and compared to the gas chromatography (gc) method. a charcoal adsorption tube connected to a small pump was used to obtain samples from an atmosphere chamber standard. samples were extracted with methanol and analyzed by hplc-uv. chromatography was is...

separation of some biogenic amines via rp-hplc using mixed micellar mobile phase was investigated. the compounds were derivatized before hand by dansyl chloride as a chromophoric reagent. appropriate conditions for separation, were determined by studying factors such as temperature, type and percentage of organic modifier, concentration of surfactants (sds and brij-35) and the ph of the mobile ...

This thesis describes efforts made on the development of an existing catalytic incinerator. The development work, called process characterization, consists of four general parts. These are the development of measurement methodology, the studying of construction materials, the selection of suitable catalysts and the testing of the effects of process operation conditions. The two application area...
