Release of cyanide from KCN into the blood stream during its usage has been found to be toxic to human health. Sequel to this, the study aims atinvestigating by spectral analysis, the cyanotoxicity effect of KCN on normal human haemoglobin. The study was divided into 8 groups consisting of control and test groups (0.2, 0.5, 1 and 1.5M KCN + 1000µl Oxyhaemoglobin respectively and 2000, 3000 and 4000µl Oxyhaemoglobin + 1.5M KCN respectively). It was found that KCN caused concentration dependent oxidation on normal human haemoglobin and also a concentration dependent reduction in oxyhaemoglobin concentration which are all precursors to several pathophysiologic conditions in man. Therefore, measures should be put in place to curtail the hazardous effect of cyanide emission on human.<#LINE#>Greim, H. (2003).@Hydrogen cyanide, potassium cyanide and sodium cyanide.

Bhilwara city is known as Textile City. The textile industries are most water and chemical intensive industry worldwide and produce large amount of waste water as colored dyes effluents. Colored effluents is toxic in nature and damage to the environment and ecosystem. For the production of 1 kg textile fabric industries consumed 200-400 litres of water. Textile effluent is contains inorganic as well as dissolved organic substances. Dark colour of waste water is due to the presence of residual dyestuffs. The photocatalytic decolorization of textile dye Methylene blue was examined by using photochemical reactor with WO3 and SnO2 photo catalyst in presence of U.V. light. The study of the effects of various environmental parameters such as type of catalyst, pH value and catalyst mass were also investigated by using spectrophotometer at different wavelengths.<#LINE#>Rauf M.A. (2009).@Fundamental principles and application of heterogeneous photocatalytic degradation of dyes in solution.@Chemical Engineering Journal, 151(1-3), 1-18.@Yes$Oviedo A.

Characterization of adsorbent was done by elemental analysis and functional groups identification techniques. The result denoted that the phosphate adsorption using Fe(III)-SMW was easily controlled by switching pH value. The hydroxyl ions were released during uptake of phosphate using Fe(III)-SMW. The maximum uptake of Fe(III)-SMW for phosphate was determined as 4.08 mgg-1using Langmuir isotherm model. Phosphate concentration after adsorption sharply decreased with increasing solid-liquid ratio and reached 100% uptake by using Fe(III)-SMW. Adsorbed phosphate anion was effectively desorbed (99.56%) by using 1M NaOH solution. Therefore, Fe(III)-SMW adsorbent seems as a promising, low-priced and potential materialto treat trace amounts of phosphate anion present in polluted water.<#LINE#>Bunce, J. T., Ndam, E., Ofiteru, I.

Oliver and Citrus reticulata Blanco. They exhibit many beneficial effects such as anti-bacterial,anti-fungal, antiseptic, anti-inflammatory, etc. Even though these Rutaceae species have extensively used in different medicinal systems, scientific information on phytochemical contents and antioxidant capacity are scattered or lacking. Hence, scientific experiments were done to investigate the phytochemicals and antioxidant potential of these five Rutaceae species grown in Sri Lanka. Both aqueous leaf extracts and leaf oil of all five Rutaceae species were subjected to Thin Layer Chromatographic (TLC) analysis and phytochemical screening using standard protocols. In addition, total phenolic content, total flavonoid content and DPPH free radical scavenging ability were investigated. Preliminary phytochemical screening revealed that presence of phenols, flavonoids, tannin, saponins, steroid glycosides, coumarins, terpenoid and alkaloids in all tested plant species except A. ceylanica. TLC fingerprint profiles of C. sinensis and C. reticulata are similar to each other. However, TLC fingerprint profiles of other tested Rutaceae species were different to each other. Further, C. reticulata exhibited the highest amount of phenols and flavonoids followed by C. aurantifolia, C. aurantium, C. sinensis and A. ceylanica respectively. Accordingly, best free radical scavenging ability was also exhibited with C. reticulata and lowest ability was exhibited with A. ceylanica. Therefore, tested Rutaceae species can be utilized in pharmaceutical and food industries in future.<#LINE#>Kankanamalage, T. N. M., Dharmadasa, R. M., Abeysinghe, D. C., & Wijesekara, R. G. S.

Plastics, rubbers, fillers, paints, coatings, resins, adhesives and blends are some examples of compounds which can be identified by using FTIR. The sensitivity of FTIR enables detection of contamination present in very small quantity which makes it a vital tool for quality control and quality assurance applications. Thus, FTIR plays an important role to compare batch-to-batch products for meeting quality standards. This paper presents application of FTIR as an effective tool for evaluation of materials. A few case studies of analysis of variety of automotive materials including contaminate analysis of brake fluid, fabric sample used in roof lining of passenger car, painted panel of fuel tank and compatibility of material with alternate fuel using FTIR are presented. The evaluation using FTIR for the above cases provided objective evidences for confirmation of probable causes for material failure.<#LINE#>Sanches, N.B., Pedro, R., Diniz, M.F., Mattos, E.C., Cassu, S.N. and Dutra, R.C.L.
