Certain plant species have been shown to vigorously accumulate some metals from soil, and thus represent promising effective remediation alternatives. In order select the optimum forms of nitrogen (N) fertilizers for arsenic (As) hyperaccumulator, Pteris vittata L., maximize As extraction, five N were added individually different treatments study effect on uptake plants under soil culture in a greenhouse. Although shoot concentration tended decrease translocation root was inhibited, overall...
With the aim of stabilizing arsenic pollution in mine tailing, FeCl<sub>2</sub> and FeCl<sub>3</sub> were chosen as stabilizers.
Ferrous chloride has been evaluated as a novel approach to stabilize arsenic in mine tailings. The influence of iron/arsenic molar ratio, pH, stabilization time, granularity, and temperature on the concentration released was evaluated. Arsenic speciation before after characterized. When ratio 1 pH between 6.5 7.5 below 50°C using time h, 2.5 mg/L which meets national Chinese standards. Hence, this enhanced stability reduced toxicity mining by-products.
Ferric nitrate–graphene (FG) nanocomposites synthesized via the equivalent‐volume impregnation method were used for removal of As(V) species from simulated arsenic‐containing wastewater. Effects various factors assessed, such as reaction temperature, solution pH, adsorbent dosage, and time. The results indicated that efficiency was high 99%, concentration wastewater after FG treatment low 9.4 μg L –1 a result optimal absorption capacity maximum specific surface area (171.766 m 2 /g) this...
