“…Thus, the highest risk of As(V) pollution from drinking water in drilled wells and village drills is lower than that in lakes or streams. As and its compounds, once they penetrate into the livings, cannot be rejected through biochemical cycles and accumulated in body, causing serious impacts [ 8 ]. At present, it is estimated that more than 150 million people in worldwide have been affected by increasingly concentration of As in drinking water [ 9 ].…”

This work reveals the As(V) adsorption behaviors onto iron oxide (Fe3O4) nanoparticles modified activated carbon (AC), originally developed from biochar (BC), as a green adsorbent denoted by FAC. Since FAC has abundant surface functional groups and a desired porous structure that is favorable for the removal of As(V) in contaminated water, FAC has greatly enhanced the As(V) adsorption capacity of the original BC. Various methods were employed to characterize the FAC characteristics and adsorption mechanism, including pHpzc determination, BET specific surface area, elemental analysis (EA), and scanning electron microscopy (SEM). Results show that the AC surface was successfully modified by iron oxide nanoparticles, enhancing the porosity and specific surface area of original adsorbent. Batch adsorption tests indicated a well-fitted Langmuir model and pseudo-second-order model for As(V) adsorption. Additionally, the highest adsorption capacity (Qmax = 32.57 mg/g) by FAC was higher than previously reported literature reviews. Until now, no article was conducted to research the effect of carbon surface chemistry and texture on As removal from waters. It is required to obtain a rational view of optimal conditions to remove As from contaminated water.

“…It also increases the catalytic active sites and improves the utilization of palladium on the polyaniline catalytic layer. 47,48 The polyaniline intermediate layer increases the activity and adhesion of the ITO conductive glass surface, 49 so that the Pd particles can be stably supported on the intermediate layer and can be better dispersed. The loading of Pd improves the charge and mass transfer process on the electrode surface, which is conducive to the diffusion of target contaminants on the electrode surface.…”

In order to treat antibiotics organic pollutants in the water environment, the Pd/PANI/ITO composite electrode was prepared by the galvanostatic electrodeposition method in this paper. The surface morphology and electrocatalytic activity of the electrode were analyzed and tested. Using the degradation rate of electrocatalytic tetracycline wastewater as an indicator, the optimal parameter conditions for preparing the composite electrode were screened out: the optimal deposition current of PANI was 2 mA, and the deposition time was 10 min. The optimal deposition current for Pd is 2 mA, and the deposition time is 10 min. The optimal current for the degradation of tetracycline wastewater is 10 mA, and the relationship between the degradation current and the degradation time conforms to the pseudo-first-order reaction kinetics. The existence of ÁOH in the degradation process of tetracycline was verified by the coumarin fluorescence detection technology. Finally, the degradation process of tetracycline wastewater is analyzed. The results show that the intermediate products produced during the degradation of tetracycline are gradually cleavage of tetracycline molecules, and they are eventually converted into CO 2 and H 2 O.

“…Nanomaterials are typically two-or threedimensional materials, of which at least one dimension is nanometers (nm). Thus, nanomaterials can exist in three states: solid, liquid, and gas, in which solid nanomaterials are being studied the most, especially in the field of application in the agricultural system of developing countries such as Vietnam [1][2][3]. The concept of nanotechnology was first introduced in 1959 by the famous physicist Richard Feynman.…”

Agricultural Restructure Policy in Vietnam and Practical Application for Sustainable Development in Agriculture

The Vietnam’s agricultural sector had to challenge with its course and learned lessons of further development. Novel policy might be adopted to encourage the private investments and sectors in agriculture. Furthermore, an introduction of new models such as climate-smart or green agriculture and application of modern technology increased productivity at the same time and creating jobs for millions of agricultural workers and reversing the massive rural-urban migration flux. Vietnam’s agricultural sector needs to maintain the reform momentum, particularly liberalization policy, and to boost up agricultural potential. Obstacles such as land limitation policy must be removed to enable large-scale production and encourage private investment in the agricultural sector. To avoid being trapped by its own success, Vietnam is now shifting the old development paradigm that focuses too much on the quantity to the quality of the agricultural production. The government makes major efforts to achieve at the same time agricultural growth, better livelihood of the farmer, and the development of the rural areas. However, Vietnam still needs to prepare a “transition strategy” to overcome the impact of the technological progress on the traditional agricultural workers.
