The method involves the reaction of V(V) with DPCI in presence of buffer solution of pH 6.8 to form colored complex with λmax at 530 nm. The fixed time method (2000 Sec) was adopted for constructing the calibration curve. The linearity range was found to be (2-12) mg/L. The correlation coefficient was 0.9999 and the limit of detection was found to be 0.349 mg/L. The method is feasible with the calibration equations obtained, which makes this method more applicable.

Upon irradiation with UV/visible light, semiconductors catalyze undergoes redox reactions in presence of air/O2 and water. In the present study Zinc oxide (ZnO) was doped with activated carbon prepared from the stem of the plant material by chemical activation namely, Vitexnegundo stem carbon (VNC). The decolourisation and degradation study of a dye namely, methylene blue (MB) was carried out to find out the efficiency of catalytic property of ZnO/VNC. The reaction was performed at 20, 40, 60 ppm of dye solution with ZnO/VNC material at 10 min interval of time. It found that the prepared ZnO / VNC composite exhibits an enhanced Photocatalytic activity for MB degradation under visible light irradiation and its photo catalysis efficiency was analyzed in specific 663 nm λ max using a UV–vis-spectrophotometer. The surface morphology and functional group present in the ZnO / VNC material was characterized by using FT-IR, SEM and XRD. The result reveals that the ZnO/VNC structure consists of irregular aggregates with rough surfaces and high photodegradation activities of ZnO/VNC on MB solutions are found to be at 20ppm.

A maximum intensity of sunlight (106.25 klux) was reached at 12:00 PM. However, beyond 12:00 PM the intensity showed a non-monotonic change behavior. This was ascribed to the change of sun position, its orientation and the direction at which the surface of the panel is illuminated. Results showed that the increase of sunlight intensity has made Isc to increase, while that of the Voc remains relatively unchanged. The reason why Isc is more affected by the sunlight intensity was understood from the fact that charge carriers acquire enough kinetic energy to move towards their corresponding electrodes before they relapse or recombine together, while as Voc is mostly correlated to the energy gap. There was a trivial decrement of efficiency with the increase of temperature. This was where the FF showeda reverse trend of increment with the increase of temperature. Noteworthy, at the points where the fill factor was decreased the efficiency was increased and vice versa.","PeriodicalId":14453,"journal":{"name":"International Letters of Chemistry, Physics and Astronomy","volume":"50 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2016-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80783085","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
