The polyethyleneimine dithiocarbamate was employed as polymers to synthesize Fe3Pt-Ag nanocomposites by using the seed deposition method. Fe3Pt-Ag nanocomposites were utilized for the catalytic degradation of methyl orange（MO） in the presence of NaBH4. Fe3Pt-Ag nanocomposites showed good chemical catalytic activity and stability in pollutants degradation. Furthermore, Fe3Pt-Ag nanocomposites can keep their efficiency till four cycles. The results suggest that the nanocatalysts with recyclability have broad prospects in environmental conservation applications.

Biomarkers of paleolake deposits from Qarhan Salt Lake in Qaidam Basin,northwest China were sys-tematically analyzed and the A―C series compounds of branched aliphatic alkanes with quaternary substituted carbon atom(BAQCs) were identified. The homologous distinguished three series,A―C,were identified as 5,5-diethylalkanes,6,6-diethylalkanes and 5-butyl,5-ethylalkanes series,and their relative abundance was A > B > C. Series A and C were characterized by odd carbon numbers,whereas series B was characterized by even carbon numbers. The high values of series A corresponded with the high values of series B and C. Therefore,it can be concluded that series A,B and C possess a similar biological origin. The abundance of series A was relatively low in the lower part of the section compared with that in the upper part,implying that these series originated from bacteria and/or algae more prevalent in fresh-mesohaline water,and such kinds of bacteria and/or algae are most likely to be thermophilous species. The A25/nC25 ratio differences in the section show that such branched aliphatic alkanes can be treated as one kind of environmental change proxy for paleolake evolution and may provide important information for the climate reconstruction of the Late Pleistocene.
