The presence of oxyanions such as phosphate (P) in soils is believed to have effects on lead (Pb) interaction with minerals and is often considered as a remediation method for Pb immobilization in soil. In this study, the effect of P on Pb sorption o

The infrared multiphoton dissociation (IRMPD) of the two isomers, M(1,3-butadiene)+ and M(C2H2)(C2H4)+ (M = Fe, Co, or Ni), was investigated. For the butadiene system, FeC4H6+ was observed to give three products, CoC4H6+ four products, and NiC4H6+ on

The infrared multiphoton dissociation (IRMPD) processes of groups 8−10 (Fe, Co, Ni) transition metal ion complexes containing acetylene and alkenes were investigated. Of the 30 ions studied, all but four were found to be photoactive at 944 cm-1, th

The gas-phase ion chemistry between a series of Fe(arene)[sup +] ions and halobenzene and dihalobenzene species was studied. Fe[sup +] in the arene complex acts as a reaction-initiating center to insert oxidatively into the phenyl-X bond (X = Cl, Br,

Presorbed phosphate significantly increases Pb sorption on the phyllosilicate kaolinite in the pH range from 4 to 8. The sorbed Pb-to-P molar ratios over this pH range stray little from the molar ratio found in the mineral pyromorphite, suggesting so
