Abstract:
Abstract The use of biosorption for the rehabilitation of polluted water and soils has recently gained popularity. Biosorption is a low-risk method that immobilizes harmful compounds by employing organic waste. Mercury contamination in Indonesia requires an immediate remedy that is both inexpensive and applicable in rural regions where pollution sources are concentrated. The current study aims to investigate the usage of various organic materials, namely rice husk charcoal, compost, coco dust, and zeolite, as biosorption agents for mercury remediation through collaboration with mercury-resista

Abstract:
The increasing contamination of soil, sediment, and water with heavy metals by natural and industrial processes is a worldwide problem. Many bacteria and microalgae have demonstrated ability to absorb toxic elements. To study mercury biosorption by bacteria Arthrobacter globiformis and microalga Spirulina platensis neutron activation analysis (NAA) was applied. The process of mercury biosorption by these media was described by Freundlich and Langmuir-Freundlich Model. Both microorganisms showed a great potential to be used as biosorbing agents for mercury removal from the environment.

The results of batch experiments were compared to our previous results obtained for powdered biomass (100% biomass material) and an important drop of sorption capacity was observed. For column experiments, the bed height and flow rate were kept constant and the influence of both initial mercury concentrat

Biosorption has great potential in removing toxic effluents from wastewater, especially heavy metal ions such as cobalt, lead, copper, mercury, cadmium, nickel and other ions. Mathematically modeling of biosorption process is essential for the economical and robust design of equipment employing the bioadsorption process. However, biosorption is a complex physicochemical process involving various transport and equilibrium processes, such as absorption, adsorption, ion exchange and surface and interfacial phenomena. The biosorption process becomes even more complex in cases of multicomponent sys

The Freundlich model described the adsorption of copper and cadmium. Whilst the Langmuir isotherm had the better fit of the mercury data. The assumptions of the Freundlich model include multi-layer adsorption and different functional group binding. Conversely the Langmuir model suggests mono-layer adsorption and can infer single group reactivity. The pH effect on

Heavy metal contamination (e.g., mercury, cadmium) presents severe environmental risks. Microbial bioremediation offers an eco-friendly solution. Microorganisms employ biosorption, bioleaching, and biotransformation mechanisms. Biosorption binds metals to cell surfaces, bioleaching leaches metals from ores, and biotransformation alters metal oxidation states. Heavy metals induce toxicity, hampering plant growth, causing health issues (e.g., cancer), and disrupting ecosystems. Microbes neutralize metals effectively.
