“…This is due to functional group that form after deprotonated and negatively charged. The functional groups include carboxyl, carbonyl, hydroxyl and other anionic ligands that interrelate with copper metal ion through adsorption at surface of LLP is confirmed negatively charged [25]. So it shows that as higher pH values that have negativity value on surface on sorbent, thus, the greater the level of adsorption of the metal.…”

In this work, the efficiency of Leucaena leucocephala pods, an agricultural waste, to remove copper (Cu) ions in aqueous solution by adsorption. Batch mode experiments were carried out at 30 ◦C to study the influence of pH, contact time (t) and dosage on the adsorption of Cu by Leucaena leucocephala pods. The surface behaviour and the composition of the Leucaena leucocephala pods was characterized using pH of point of zero charge (pHPZC), Fourier transform infrared spectroscopy (FTIR). It is shown that Leucaena leucocephala pods adsorbent can effectively remove Cu from aqueous solutions. The best sorption results were obtained at pH 8.0 , 0.75 g dosage and within time 80 min. The FTIR studies indicated was existence of surface hydroxyl, carboxyl and carbonyl groups. Adsorption method was used to successfully execute post adsorption elution of the loaded metal.

“…Indigo carmine (IC) dye is widely present in wastewater produced from textile, food, cosmetic, pharmaceutical and paper industries [8][9][10][11][12]. According to WHO, the permissible limit of indigo carmine dye is 5 μg L − 1 in water [13]. Wastewater containing IC dye must undergo treatment before discharging into the environment as it may cause skin and eye irritation, cancer to human [14][15][16].…”

The present work determines efficiency of domestic food waste like tea waste in removing indigo carmine from synthetic textile wastewater. Carbonaceous material (tea waste) has been employed and it showed removal percentage of indigo carmine at 90% through adsorption process. Carbonaceous material was chemically activated by using modified Hummer’s method and it was observed through Scanning Electron Microscopic image, Fourier Transform Infrared Spectrometer, X-ray diffractometer and Brunauer, Emmett and Teller analysis that revealed that the modified biochar is comparably similar to graphene oxide (GO). Various experimental parameters are evaluated for the removal efficiency of the synthesized adsorbent under the present study. Results of the experiments performed using the GO-like adsorbent synthesized from tea waste confirmed potential efficiency of adsorption of indigo carmine dye from synthetic waste water solution. The adsorption mechanism has been analysed by fitting the experimental data in different adsorption isotherm and kinetic models. The results indicated that the adsorption followed Langmuir isotherm model with maximum uptake of 20 mg g− 1 and pseudo second order kinetic model with the best correlation coefficient. The thermodynamic study showed the dye removal to be spontaneous and endothermic.

“…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.
