Converting toxic Cr (VI) to benign Cr (III) would offer a solution to decontaminate drinking
water. Electrochemical methods are ideally suited to carry out this reduction without added …

In recent years, the extensive use of chromium in industrial processes has led to the
promotion of several directives and recommendations by the European Union, that try to limit …

This chapter focuses mainly on the basic principles and methods of X‐ray absorption near
edge structure and extended X‐ray absorption fine structure spectroscopy of soils, minerals …

Sediments from a high-level nuclear waste plume were collected as part of investigations to
evaluate the potential fate and migration of contaminants in the subsurface. The plume …

Metals play important but varied roles in human health. Some metals are required for normal
metabolic function, with optimal amounts for maximum benefit. Others are only known to …

Chromium reaches the soil environment through waste disposal emanating from a number
of industrial activities, including coal-fired power production, electroplating, leather tanning …

Strontium-90 is a beta emitting radionuclide produced during nuclear fission, and is a
problem contaminant at many nuclear facilities. Transport of 90Sr in groundwaters is …

This study investigated Cr (VI) reduction and immobilization by magnetite under alkaline pH
conditions similar to those present at the Hanford site. Compared to acidic and neutral pH …

The availability of synchrotron radiation (SR) to the scientific community has literally
revolutionized the way X-ray science is done in many disciplines, including low temperature …

The influence of Al (OH) 4− on the dissolution rate of quartz at pH 10–13 and 59–89° C was
determined using batch experiments. Al (OH) 4− at concentrations below gibbsite solubility …
