“…The adsorption of copper(II) ions onto HAp/BC adsorption process followed the pseudo-second-order model with the maximum adsorption capacity of 99.01 mg/g at 298 K [86,87] . Wang et al [88] prepared HAp microspheres for the removal of coomassie brilliant blue (CBB) from wastewater. Adsorption of CBB onto HAp microspheres was found to be an endothermic and spontaneous process, with HAp microspheres having a maximum adsorption capacity of 83.8169 mg/g for CBB.…”

Hydroxyapatite is a naturally occurring calcium phosphate widely used in biomedical applications because of its osteoconductivity, biocompatibility and it possesses the closest chemical similarity to natural bone. Hydroxyapatite is also a versatile material and can be used in a plethora of ways beyond biomedical applications. This review summarises the applications of hydroxyapatite in biomedical, bioimaging, separation, purification, catalysis, surface treatment and energy storage applications. Finally, this review aims to shed light on its potential for new applications of hydroxyapatite in the future.

“…Heavy metal ions (HMs) in soils have a long residual period and strong toxicity and easily migrate, which makes heavy metal pollutants easily flow into the food chain and ultimately affect human life and health (Huang et al, 2020a;Huang et al, 2020b;Khirul et al, 2020;Wang et al, 2021;Deng et al, 2022). A large part of the land polluted by heavy metals is cultivated land and accounts for 8% of the total cultivated land in China (Liu, 2015;Yu et al, 2021;Bai et al, 2022a), resulting in the reduction of grain production and the decline of grain quality (Jiang et al, 2018;Huang et al, 2020c;Rodriguez-Arellao et al, 2021;Wang et al, 2022). According to the Bulletin of National Soil Pollution Survey, the total soil that exceeds the Chinese standard of soil pollution is as high as 16.1%.…”

The adsorption capacity of oyster shell powders (SPs) and the adsorption mechanism of heavy metal ions (HMs; i.e., cadmium ions Cd2+ and lead ions Pb2+) on SPs are discussed by means of adsorption kinetics tests, adsorption-desorption tests, scanning electron microscopy and Fourier transform infrared spectroscopy. The influences of seepage velocity, heavy metal types, and SP addition amount/concentration on the adsorption effect of SPs in the treatment of HMs in laterite as well as quartz sand were analyzed. Studies have shown that i) the adsorption of HMs on SPs can be divided into three stages, i.e., the surface adsorption stage, the internal pore diffusion stage, and the equilibrium stage; ii) with the increase in seepage velocity, the effluent concentration of HMs will slightly increase, and the residual amounts at each section of the column generally decrease rapidly with the increase in migration distance; iii) the increase in the concentration of SP solution provides more adsorption points for the adsorption of HMs, and finally, the amount of HMs desorbed from quartz sand is reduced, which also reduces the concentration of HMs in the effluent. Overall, SPs possess high purification efficiency for the HMs of contaminated soils.

“…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.…”

A Critical Review of Snail Shell Material Modification for Applications in Wastewater Treatment

2023

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.
