“…Currently, various methods can be adopted to remove Pb 2+ in oral medical wastewater, including ion exchange (Pember et al 2016), liquid-liquid extraction (Soniya et al 2015), membrane filtration (Li et al 2016), biosorption (Oguntimein et al 2015), electrodialysis (Deghles et al 2016), electrocoagulation (Ghanbari et al 2015), and adsorption technology (Zhu et al 2018;Ghasemi et al Fuxiang Song and Na Wang these authors and institutions have equally contributed to this paper. 2018).…”

“…2018). However, most of them have some disadvantages, such as high operating cost, low processing efficiency, and the possibility of secondary pollution like toxic products (Zhu et al 2018), thus limiting their applications in practice. Adsorption technology, however, has become one of the most popular and promising method due to the properties of low cost, high adsorption efficiency, and convenient operation (Zhu et al 2018).…”

Oral medical wastewater with heavy metal ions (such as plumbum, Pb2+) is regarded as the main pollutant produced in the oral cavity diagnosis, and the treatment process can pose a serious threat to human health. The removal of Pb2+ from oral medical wastewater facing major difficulties and challenges. Therefore, it is of great significance to take effective measures to remove Pb2+ by using effective methods. A new activated three-dimensional framework carbon (3D AFC), regarded as the main material to remove Pb2+ in the oral medical wastewater, has been fabricated successfully. In this experiment, the effects of 3D AFC absorbing Pb2+ under different conditions (including solid-to-liquid ratio, pH, ionic strength, contact time, and initial concentration, etc.) were discussed. And the result revealed that the adsorption kinetics process of Pb2+ on 3D AFC conformed to the pseudo-second-order model and the adsorption isotherm conformed to the Freundlich model. Under the condition that pH = 5.5 and T = 298 k, the calculated maximum adsorption capacity of 3D AFC for Pb2+ was 270.88 mg/g. In practical application, it has strong adsorption ability for Pb2+ in oral medical wastewater. Thus, 3D AFC shows promise for Pb2+ remove and recovery applications because of high adsorption capacity for Pb2+ in oral medical wastewater due to its high specific surface area, outstanding three-dimensional network structure.

“…The literature mentions different substances used as a template [18][19][20][21][22][23][24][25]40 which aims to improve some properties of the material, changing its morphology, increasing the specific surface area and pore size, and also decreasing the particle size. Some additives/templates used, such as surfactants, may have elements that can be difficult to remove, contaminating the biomaterial.…”

“…Thus, the removal of lead from liquid effluents has an interest of the uttermost importance, and this task had been recently investigated using primarily, ion exchange or adsorption of the metal by various materials (Alexander et al, 2018;Chanthapon et al, 2018;Chen et al, 2018;Chu et al, 2018;Cunha et al, 2018;El-Bahy, 2018;Elsherbiny, et al, 2018;Fang et al,. 2018;Feng et al, 2018;Georgescu et al, 2018;Gupta et al, 2018;Hayeeye et al, 2018;He et al, 2018;Huang and Wang, 2018;Kragović et al, 2018;Kinnarinen et al, 2018;Kulkarni et al, 2018;Li et al, 2018;Liu et al, 2018a;Liu et al, 2018b;Magrì et al, 2018;Quyen et al, 2018;Rajamohan et al, 2018;Rehman, et al, 2018;Rwiza et al, 2018;Sahmoune, 2018;Song et al, 2018;Tran et al, 2018;Wang et al, 2018a;Wang et al, 2018b;Yang et al, 2018;Ivanenko et al, 2018;Zhou et al, 2018;Zhu et al, 2018) liquid membranes (Ershad et al, 2018;Mesli and Belkhouche, 2018), and electrochemically (Oke et al, 2017).…”

El plomo está considerado como un metal altamente peligroso para los seres humano, por lo que su eliminación, de cualquier medio que lo contenga, suele ser de la máxima importancia. Comúnmente y a valores de pH inferiores a 5-6, este elemento esta presente en los medios acuosos como catión Pb2+. En el presente trabajo se investiga la eliminación de este catión de disoluciones acuosas empleando la tecnología de cambio iónico con la resina Amberlite IR-120. Se consideran una serie de variables que pueden afectar al proceso de carga del metal en la resina: velocidad de agitación del sistema, temperatura, dosificación de la resina y tamaño de partícula de la misma y pH del medio acuoso. La carga del metal responde a la isoterma de Freundlich, siendo el proceso endotérmico y no espontáneo, el mecanismo de carga no depende del tamaño de partícula de la resina y responde a un mecanismo por difusión en el medio acuoso. La eliminación del plomo(II) de disoluciones acuosas mediante la resina compite de forma favorable con respecto a los resultados obtenidos cuando se emplean nanotubos de carbono de pared múltiple como adsorbentes del Pb2+. En ensayos llevado a cabo con disoluciones binarias, la carga del Pb2+ en la resina también compite favorablemente con respecto a la de otros metales base en forma catiónica. La elución del plomo(II) se puede llevar a cabo de forma casi cuantitativa con disoluciones de HCl y distintas condiciones experimentales.
