Microstructural analysis proved the presence of calcium carbonate in the form of calcite, confirming removal of cadmium and arsenic by microbially induced calcium carbonate precipitation (MICCP) to be promising technique for water decontamination.

Batch experiments were conducted to study the effect of solution pH on the removal of lead, cadmium, and arsenic at initial pH range from 3 to 9, where the sorbate concentration was taken as 5.72, 5.28 and 6.74 mg/L respectively. The percentage removal results of these toxic pollutants as a function of initial pH was shown in Fig. 7 a.

Arsenic (As) and cadmium (Cd) are toxic elements and well-known human carcinogens. Due to natural factors and human activities, they both contribute to environmental pollution, posing a health risk for animals and humans mainly through contaminated water and food. Because they are odorless and tasteless, their excessive …

REMOVAL OF CADMIUM, LEAD AND ARSENIC FROM WATER BY LACTIC ACID BACTERIA. T. Halttunen. Published 28 January 2008. Environmental …

The concurrent presence of arsenic (As) and cadmium (Cd) contamination in soil is widespread and severe, highlighting the need for remediation. However, remediating As and Cd co-contaminated soils is more complex than remediating soils contaminated with a single heavy metal due to the opposite properties of As and Cd in …

The optimal soil washing option for arsenic and cadmium was identified as phosphoric-oxalic acid-Na2 EDTA sequence (POE) based on the high removal efficiency (41.9% for arsenic and 89.6% for cadmium) and the minimal harmful effects of the …
