“…However, in recent years, the use of adsorbent materials from the sea has been focused on due to treatment efficiency as well as solving environmental problems [ 47 ]. Shrimp [ 48 , 49 , 50 ], crabs [ 51 , 52 ], oysters [ 53 , 54 ], snails [ 55 , 56 ], clams [ 57 , 58 ], fish bone [ 59 , 60 ], and other marine species [ 61 , 62 , 63 ] are used as highly effective adsorbents in the removal of wastes from water pollution.…”

Sea material is becoming increasingly popular and widely used as an adsorbent in wastewater treatment. Snail shell, a low-cost and natural animal waste material, has been shown to have a high calcium content (>99%) and a large potential surface area for the development of sustainable adsorbents. This paper presents a novel synthesis of methods for using snail shell absorbent materials in the treatment of wastewater containing heavy metals, textile dyes, and other organic substances. Modified biochar made from snail shells has gained popularity in recent years due to its numerous benefits. This paper discusses and analyzes modification methods, including impregnating with supplements, combining other adsorbents, synthesis of hydroxyapatite, co-precipitation, and the sol–gel method. The analysis of factors influencing adsorption efficiency revealed that pH, contact time, temperature, initial concentration, and adsorbent dose all have a significant impact on the adsorption process. Future research directions are also discussed in this paper as a result of presenting challenges for current snail adsorbents.

Bone biochare is used widely as an adsorbent in water pollution control; because of its high surface area and pore volumes . This study is attempting to prepare a low cost adsorbent from waste fish bone by chemical activation, and uses it for the removal of Pb and Cd from polluted water. Two methods were used for preparation of fish bone adsorbents. The first method includes the chemical activation of waste fish bone using different chemical activators ( 0.001 M HNO3, 0.1 M NaOH, 0.5 % H2O2, and ethanol), while the second one includes calcination of waste fish bone after the chemical activation at 600oC. The synthesized fish bone adsorbents were characterized by electron microscopy (SEM), X-ray diffractometer (XRD), X-ray fluorescence (XRF), BET surface area, and Fourier transform infrared (FT-IR). The efficiency of the prepared adsorbents for removal of Pb and Cd were investigated as a function of contact time, solution pH, solution temperature, initial metal concentration, and adsorbent dose. Metal concentrations were measured by atomic absorption spectroscopy . The results reveal that activation of the waste fish bone by 0.1 M NaOH is the suitable for the higher adsorption of Pb and Cd than with the other activators. The maximum adsorption of Pb and Cd on the chemically prepared adsorbent were 99.74 and 99.35 % , respectively at optimum conditions. The results of kinetic adsorption obeyed a pseudo-second-order model. Freundlich and Langmuir isotherms were applied , and the adsorption was found to be fitted well with the Langmuir model. This study ended with the success for preparing an ecofriendly and low cost fish bone adsorbent from the waste fish bone, and used it for the removal of Pb and Cd from polluted water
