At first it may seem rather strange to treat the chemistry of the halogens and the noble gases,two groups that represent the extremes of chemical activity and inertia ,in the same section .the superficial differences between the halogens and the noble gases are much reduced,however if we focus our attention on the comparison of halide ions(particularly F-) with the isoelectronic noble gas atoms and the noble gas compounds with halogen atoms or the halogens in their higher positive-oxdation states.

The study showed that the biosorption process could be described well by pseudo-second-order kinetic model and Freundlich isotherm model.Higher cell concentration was favorable to the biosorption.Temperature's effect on the biosorption was not obvious.The oxygenous and nitrogenous functional groups on the cell wall played a very important role in the process of biosorption.Microdeposits were formed by int...
