“…Furthermore, BC has recently used as supporting materials [21], [22]. In other hands, BC were reported used as an adsorbent to remove heavy metals [9], [23] and organic waste [20], [24], [25]. In present work, CuAl LDH used to load BC to enhance the effectivity to remove malachite green in wastewater.…”

“…Biochar (BC) is carbon-based compound from pyrolysis of biomass at high temperature. BC is an attractive carbon rich material from agricultural waste and 5 industrial by-product that can be use in material modification [20]. BC has been known for its application on wastewater treatment, soil and sediment adsorption.…”

In this work, CuAl/Biochar (BC) composite was prepared by the coprecipitation method. The materials were applied to remove malachite green in aqueous solution. These materials were characterized using XRD, FTIR, BET and SEM-EDX analyses. The composite material was confirmed by X-ray diffractograms with reflection (002) at 24o and the appearance of new peaks at 1095 cm -1 . The BET result of CuAl/BC composite has larger surface area is 168 m 2 /g than 46 m 2 /g for LDH. The morphologies of composite materials show agglomeration and micro particle size. The result of the adsorption study indicated the composite material follows pseudo-second-order (PSO) and Langmuir isotherm models. The maximum adsorption capacity of malachite green using CuAl/BC uptake is 164.316 mg/g. The thermodynamic analysis indicates that the malachite green adsorption is spontaneous, endothermic. Regeneration study of adsorbent CuAl/BC composite shows after four times reused, it still has high removal efficiency at 89%.

“…In contrast, it occurs only as a monolayer, and adsorbates are hardly removed because of the strong interaction. Both processes can occur simultaneously or alternatively, depending on the circumstances [43]. To study on adsorption method, one should consider the factors that affect the adsorption process, such as (i) surface area, (ii) nature and initial concentration of adsorbate, (iii) solution pH, (iv) temperature, (v) interfering substances, and (vi) nature and dose of adsorbent [44].…”

This review covers various methods to remove, treat, and detect emerging contaminants (ECs) in water and wastewater. ECs have drawn the attention of many countries due to their potential threat to human health as well as the environment. They are found in many human everyday products that are continuously released into the environment and will accumulate over time. In order to remove ECs, a number of methods have been developed, which include adsorption, membrane technology, biological treatment, and advanced oxidation process. In addition, advances in detection techniques and instrumentation are now able to detect ECs in which they occur at low concentrations. All the removal, treatment, and detection methods will be covered in this review. The removal, treatment, and detection of ECs and their transformation products in water and wastewater are challenging tasks due to their complexity in water samples. Therefore, such information should be emphasized in order to improve the current methods and develop new advanced methods.

“…Figure 2 demonstrates the typical mechanism of adsorption where the sorbate molecules covers the solid to form a film on the surface of the adsorbent (Lowell et al, 2004). Good mechanical properties such as abrasion resistance are also needed for the adsorbent to be effectively used for a great number of times (Tareq et al, 2019). There are many types of adsorbents for great number of different applications.…”

Applications of Metal Organic Frameworks in Wastewater Treatment: A Review on Adsorption and Photodegradation

et al. 2020

The growing accumulation of emerging contaminants in the environment can cause direct and indirect water pollution that puts human lives at risk. The fact that these contaminants are not or cannot be eliminated from the municipal water utilities, poses a significant concern. Researchers are currently pulling massive attention to improve existing technologies, develop new strategies, and provide environmentally durable solutions to mitigate water contamination problems. Adsorption and photodegradation are two of the most sustainable technologies that are used in water purification. These technologies have many advantages because of the economic, simple, and easily operated designs needed to treat wastewater. Within these applications, metal organic frameworks (MOFs) are playing a significant role as novel class of porous materials characterized by a crystalline structure. MOFs are considered good candidates to be employed in wastewater treatment technologies because of the tunability of their features. The scope of this review article is to provide a comprehensive description of the recent studies published in the literature about the adsorptive and photocatalytic use of MOFs for the removal of organic emerging contaminants from wastewater. Furthermore, this study briefly highlights the synthesis technologies of MOFs. Finally, future perspective and challenges associated with MOF large-scale production are discussed.
