废重整催化剂中铂的分光光度法的测定

分光光度法测定用于废氧化铝载体铂催化剂中铂含量。铂被还原成铂黑从杂质中分离出，用王水溶解形成六氯铂酸盐酸溶液，加入氯化亚锡形成橙黄色络合物溶液在４０３ｎｍ进行测定。对该方法的回收率，钼存在对测定的影响进行了研究，方法回收率９８～１０２％，在１０－６数量级，即使钼浓度与铂浓度相等并不影响铂的测定     

Technical foundation research on high resolution remote sensing system of China''s coastal zone

China‘s coastal zone is a region with a highly developed economy that contrasts clearly with the slow paced regular investigation on its natural environment, which cannot keep pace with the requirement of economic development and modem management.Laying a theoretical foundation for the modem management of China‘s costal zone is aimed at.This research focuses on the following processing and analyzing technologies for coastal zone high-resolution remote sensing data: organization and management of large amounts of high-resolution remote sensing data, quick and precise spatial positioning system,algorithms for image fusion in feature level and coastal zone feature extraction. They will form a technical foundation of the system. And, if combined with other research results such as coastal zone remote sensing classification system and its mapping subsystem, an advanced technical frame for remote sensing investigation of coastal zone resource will be constructed.     

Carbon Isotope Stratigraphy of the Cambrian System in the Eastern Tarim Basin, China

The ultra-deep Cambrian System in the Tarim Basin is an important field for petroleum exploration, while fine division of the Cambrian strata remains controversial. In recent years, carbon isotope stratigraphy of the Cambrian System has been established and widely used. Here, we report an integrated profile of carbonate and organic carbon isotopic values (δ13Ccarb and δ13Corg) from cuttings of the Tadong2 Well in the eastern Tarim Basin. Three carbon isotope anomalies of BACE, ROECE and SPICE were recognized on the δ13Ccarb profile. Three apogees and a nadir on the δ13Corg profile and the onset of ROECE on the δ13Ccarb profile were suggested as boundaries of the present four series of the Cambrian System. Suggested boundaries are easily identifiable on the gamma logging profile and is consistent with the previous division scheme, based on biostratigraphic evidence in outcrop sections. Abnormal carbon cycle perturbations and organic carbon burials during the BACE and SPICE events might be related to the reduction and expansion of a huge dissolved organic carbon reservoir in the deep ocean of the ancient Tarim Basin.     

Petroleum Retention,Intraformational Migration and Segmented Accumulation within the Organic-rich Shale in the Cretaceous Qingshankou Formation of the Gulong Sag,Songliao Basin,Northeast China

In this study, organic geochemical and petrological analyses were conducted on 111 shale samples from a well to understand the retention, intraformational migration and segmented accumulation(shale oil enrichment in different intervals is unconnected) features of shale oil within the organic-rich shale in the Qingshankou Formation of the Gulong Sag. Our study shows that retained petroleum characteristics in the investigated succession are mainly influenced by three factors: organic richness, int...
