Chitosan and chitin are mainly extracted from shells of fish such as lobsters, crabs or shrimps. Originally, the raw material and the two compounds are identical. This study aims to show the acid concentration effect on chitosan extraction from shrimp shells between concentrated and diluted acid; on surface morphology, thermal resistance, structural, elemental composition, optical and opto-electronic properties. It also aims to reduce the production time and increase the quantity. We focused mainly on comparing between Physico-chemical properties of chitosans extracted by diluted (1M) and concentrated (20%) Chloric acids, and sometimes we compare by other concentrated acids like nitric acid (70%) and sulphuric acid (98%). We performed the product's characterization by various tools such as: X-ray diffraction (XRD) spectroscopy, X-ray fluorescence (XRF) analysis, UV-Visible spectroscopy, Fourier Transformed Infra-Red (FTIR), Raman Spectroscopy, Thermogravimetry and Derivative Thermogravimetry (TG/DTG), Scanning Electron Microscopy (SEM), Energy-dispersive X-ray spectroscopy (EDX) analysis. The elemental analysis (XRF and EDX). The results showed that all chitosan samples we gained are good about 80% degree of deacetylation, and pure mostly composed by carbon between (15,02% -45.55%), nitrogen (4,17% -12.28%) and oxygen (42.16% and 81.25%), with appearance of essential peaks for chitosan in Raman analysis: 470 cm À1 → ν(C-C(¼O)-C), 1000 cm À1 → ν(C-H), 1800 cm À1 → δ(C¼CCOOR), δ(C¼O), 2630 cm À1 → δ(CH) rings, 3250 cm À1 → ν(NH 2 ). All our chitosan particles are ultrafine nanoscale between 8 and 34 nm.

Iron‐based magnetic nanoparticles (MNPs) have been studied extensively for the past few decades. They have been applied in various applications, particularly in the biomedical sector. Due to their excellent physical and chemical properties, they have also been used widely in the agricultural sector. MNPs can be synthesized inexpensively and applied in large scale agricultural activities. This paper highlights the applications of iron‐based MNPs in the agricultural sector mainly as antimicrobial agents, plant growth promoters, site‐targeted delivery agents, nanosensors, detection and remediation for pesticide residue. Furthermore, the toxicity and transport of iron‐based MNPs in the soil‐plant system are also elucidated. These aspects have to be well‐understood before MNPs can be fully implemented effectively this pin the agricultural sector. Lastly, a hybrid nanomaterial, which is consisted of iron and magnesium oxide (MgO) nanoparticles (NPs), is proposed. This hybrid nanomaterial is expected to overcome the shortcomings of iron‐based MNPs.

“…The use of MG in aquaculture companies is prohibited in several countries and its tolerance limit in water bodies was established at a concentration of 0.5-100 μg L À1 (Zhang et al 2017). Thus, specific monitoring of MG consumption and its removal from industrial wastewater should be considered, due to its extensive destructive effects on the environment and health of fish and mammals (Salamat et al 2019).…”

The use of ionic flocculation is proposed to remove malachite green (MG), in this case, from water. A surfactant with the polluted solution and calcium is added. The surfactant-calcium reaction forms a precipitate, which aggregates into flocs on agitation. The flocs adsorb MG, which can then be removed by centrifugation. Ionic flocculation was assessed by varying parameters including: surfactant and MG concentrations, electrolyte content, pH, contact time, etc. The isotherm and adsorption kinetic models that best fit this process are the Langmuir and pseudo-second order models, respectively. MG removal efficiency of 96% was obtained at pH 9, with surfactant concentration 1,400 mg L−1, MG concentration 10 mg L−1 and contact time 10 minutes. The process has potential for pollutant removal.
