“…It is expected to be a promising reusable adsorbent. The adsorption kinetics of methyl orange on rambutan-like MnCo 2 O 4 was interpreted by the pseudo-first-and secondorder rate equations [23,31,32]. The adsorption activation energy E a and mechanisms of methyl orange on the rambutan-like MnCo 2 O 4 are discussed in this paper for the first time.…”

“…Therefore, synthesis of ferrites with high surface area is the key to improve the adsorption capacity of ferrites. It was reported that ferrite with 3D porous structure could have high efficient adsorption property due to its large specific surface area [23]. MnCo 2 O 4 is a very important mixed metal oxide with an inverse spinel structure and magnetic property.…”

A hierarchical rambutan-like MnCo 2 O 4 precursor is synthesized by a co-precipitation method in water-ethanol at room temperature. After being calcined at 400°C in air for 10 min with a heating rate of 1°C min -1 , the precursor MnCo 2 (C 2 O 4 ) 3 Á5.54H 2 O is transformed into the rambutan-like MnCo 2 O 4 microspheres composed of end-connected nanorods, which has a large specific surface area (155 m 2 g -1 ). When evaluated as adsorbent for methyl orange (MO), the rambutan-like MnCo 2 O 4 microspheres show excellent adsorption ability for methyl orange. The adsorption capacity of methyl orange on rambutan-like MnCo 2 O 4 is 185.14 mg g -1 under the conditions of initial MO concentration 12 mg L -1 and pH 2.09. Adsorption kinetics of methyl orange on rambutan-like MnCo 2 O 4 follows the pseudo-second-order kinetic model. The values of adsorption activation energy E a and enthalpy DH # are 5.71 ± 0.056 and 9.30 kJ mol -1 , respectively. Methyl orange adsorption on rambutan-like MnCo 2 O 4 is an endothermic and physical adsorption process.

The water treatment process by removing heavy metals from polluted sources is explained in detail. Various detection and removal techniques and their modeling for heavy metal removal are reviewed. Detection of heavy metals is possible by several optical, spectroscopic and electrochemical methods. Due to their high efficiencies and accurate evaluation capabilities, several spectroscopic as well as other techniques like neutron activation analysis and X‐ray fluorescence are discussed and found highly significant. Adsorption, photocatalysis, ion exchange, electrochemical methods, membrane filtration, chemical precipitation, and forward osmosis are the most frequently used techniques for heavy metal removal, being up to 100 % efficient to detect and remove heavy metal ions. The design, operation, and key features of all techniques are explained. The regeneration of used adsorbents, resins, and other materials to remove heavy metals is found as key step in the wastewater treatment process.
