Organic Matter in Carbonaceous Chondrites
1986Carbonaceous chondrites are objects of great interest for chemists and astrophysicists. They contain a large number of abiogenic organic molecules and they are fragments of the least metamorphized bodies which exist in the solar system. Therefore, the study of carbonaceous chondrites affords information about the state of matter 4.5 Gyr ago.

[Effect of extracelluar organic matter and natural organic matter on coagulation].
Huan jing ke xue= Huanjing kexue, 2011Influence of EOM and NOM on removal of algae and turbidity was investigated. The result showed that EOM had both beneficial and harmful effects on coagulation, it hindered the charge neutrality of the flocculant. Zeta potential of algae decreased from -40.6 mV to -14.7 mV, only when the modified chitosan was added above 0.2 mg x L(-1).
