Abstract:
... Low molar mass carbonyl telechelic cis,1–4 polyisoprene (CTPI) and aldehyde telechelic cis, 1–4 polybutadiene (ATPB) were easily prepared by the controlled degradation of high molar mass 1,4-cis polyisoprene (PI) and 1,4-cis polybutadiene (PB) in a molar mass range of 5000–80 000 g mol⁻¹. Two methods are compared: the direct one using only the periodic acid (H5IO6) to randomly cleave the chain and ...

Abstract:
... Soil washing has been developed as one of the ex situ traditional remediation methods for heavy metal polluted soils. It has been found to be effective in metal extraction. However, due to the distribution and speciation in soils, most metal(loid)s are present in less mobile forms which limit the washing efficiency. Therefore, methods are studied to enhance the washing performance by increasing th ...
