Decomposition characteristics of humic acid in boiler

2018-1-5 · Humic acid purchased from Aldrich Chemical Co. Ltd. The mass fraction of HA (Sigma–Aldrich, Steinheim, Germany) in the experiment was 81.7%. So the HA was further purified to remove ash by following the procedure described by Nash et al.. And the low-ash humic acid solid was washed with ultra-pure water to remove all anions.

Phytostabilization of heavy metals: role of plant roots

Phytomanagement refers to a group of techniques which use plants to reduce content or toxicity of heavy metals in soils. This thesis focuses on metal phytostabilization, which aims at reducing metal bioavailability in soil. Phytostabilization can occur either in roots or in soils. The first requires the uptake of pollutants and their stable accumulation in root tissues (in-planta
