(572n) Chicken Bone-Based Adsorbent for Adsorption of Metal Ion Liquid Waste

Because heavy metals have detrimental effects on aquatic life and public health, their presence in freshwater sources is extremely concerning. Even in low quantities, copper (Cu), one of the most hazardous heavy metals, can result in major health problems. The current study seeks to create a novel adsorption medium using iron (Fe)-coated chicken bones Using magnesium hydroxides, copper can be eliminated from water. In which the chicken bones were treated with stacked double hydroxides (LDH) Physical adsorption is the process by which heavy metals from the waste liquid are adsorbed onto the chicken bone-based adsorbent. The cause of physical adsorption is an imbalance in the porous nature of the adsorbent surface, which draws the adsorbate (heavy metal) to the surface. The residue of inorganic materials left over after burning at temperatures higher than 575°C is known as ash. A substance is heated as part of the ash-making process, and the method involves drying, burning charcoal, and desolating volatile chemicals. Heat will be produced by burning the charcoal, volatile chemicals will evaporate, and moisture will be lost throughout the drying process. There will be an interaction between carbon and oxygen during the burning of charcoal to form co-gas, which then develops into CO2 gas so that in the end there will be only material known as ash. With a rough and porous surface shape, apatite carbonate compound minerals are a distinguishing feature of the adsorbent made from chicken
bone ash. The adsorption performance can be improved by raising the ashing temperature, contact time, particle size, and weight of the adsorbent. The physical adsorption process is accelerated at near-neutral pH values. Adsorbents made of chicken bone ash can lower Cu metal levels while also improving waste quality.
In this paper, Carbon-based adsorption is described as a traditional treatment with a high unit cost, particularly in underdeveloped nations.

Contamination of metals, in water is a pressing concern for both the environment and public health. Several metals, including lead, mercury, arsenic, cadmium, and copper pose risks. These metals can find their way into water sources through processes well as industrial activities, mining operations, and agricultural runoff. Consuming drinking water with levels of metal contamination can result in health issues such as neurological problems, developmental disorders organ damage, and an increased risk of cancer. Furthermore, aquatic ecosystems are also adversely affected by metal contamination which impacts the well-being of fish and other aquatic organisms. Therefore it is crucial to address and mitigate metal contamination, to protect health and preserve the environment. Increased production of broiler chicken meat seems to be a result of Egyptians' rising consumption, which will lead to a rise in the amount of discarded chicken bones that cannot be recycled. Crystalline salt minerals in the form of calcium phosphate complexes, which are frequently idealized as hydroxyapatite, make up the majority of the inorganic phase of bone. Because the hydroxyapatite mineral has a porous surface and is a bioceramic material, it can function as an adsorbent. Metals in liquid waste can be adsorbed by this adsorbent, among its other uses. Liquid waste is produced by the manufacturing process, cleaning of production equipment, laboratory operations, and residual products that are deemed to be of low quality or that result from production process failure. among other sources within the petrochemicals industry sector. One alternative way is using waste treatment sorption. Adsorption using carbon is stated as a conventional treatment which has a high unit cost, especially in developing countries. This research was conducted to examine the possibility of recycling chicken bones for use in water treatment by coating the bones with iron and magnesium hydroxide layers.This new adsorption medium was applied to remove copper from a water sample. Thus, this adsorption medium could be an eco-friendly and economically efficient alternative to the current methods for the removal of heavy metals from water.
