Abstract- Presence heavy metals are not acceptable in water so, this study presents removal of heavy metals from water with the use of different adsorbents, particularly agricultural waste materials. This is to develop effective and economical water treatment solutions. The hazardous effects of presence of heavy metal in water causes great risks to source of water and health issues to human. In regions like Bhandara and Ambazari Lake in Nagpur, groundwater has been found to contain iron concentrations significantly exceeding the permissible limit of 0.3 mg/L. Specifically, Bhandara's groundwater contains approximately 17 mg/L, while Ambazari Lake has about 1.16 mg/L. Such high levels of iron not only affect the taste and color of water but also pose health risks to the local population. The study investigates the use of coconut coir, an agricultural waste product, as a solid-phase extractor for the removal of total iron from water. Good binding property is found in coconut coir which is capable to remove iron, also leads to economical and proven good adsorbent. Presemt research analyses different parameters which governs adsorption efficiency, like pH, adsorbent dosage, contact time, and initial iron concentration. It has been observed that the water having pH between 4-5 allows maximum removal of iron. With satisfactory conditions, heavy metal removal efficiency by coconut coir is 96%. For iron-contaminated water study provides the capability of coconut coir i,e. a good adsorbent for treatment.
