Study The Negative Effect of the Accumulation of Iron and Manganese Ions in Groundwater Irrigation with Treatment by Magnetic Nanomaterials and Its Relationship of Surface and Subsurface Soils Characteristics

Abstract

The article's goal was to examine the treatment of contaminated groundwater and its connection to soil characterization. The production of crops was negatively impacted by the accumulation of iron metal in soil and groundwater, necessitating treatment and crop selection. Titania-coated cobalt ferrite nanocomposite for treating contaminated groundwater was created using the sol gel technique. Particle size distribution, BET, FTIR, SEM, XRD, VSM, and EDX techniques were used to characterize the prepared nanocomposite. The solution's pH, contact time, amount of adsorbent, initial ion concentration, and temperature were all examined. Fe (II) and Mn (II) ion maximum adsorption capacities ranged from 83% to 94% mg/g once the ideal adsorption conditions were identified and applied. When reclaiming our lands, it is important to assess the soil resources to determine whether the land is suitable for growing crops. In the Dakhla-Abu Minqar District, Western Desert, Egypt, soil properties are assessed and analyzed for the majority of irrigated crops; land capability and suitability for crops maps are created using the Geographic Information System. The Geographic Information System (GIS) is used to create land suitability maps, and the majority of irrigated according to Applied System of Land Evaluation (ASLE) program, and evaluation of their soil properties. The study's findings showed that the area is currently land capability fair (Class 3) to very poor soils (C5), while suitable (S2) and marginally suitable (S4) for permanent and semi-annual crops. Soil depth, soil salinity, drainage, and texture were the primary constraints found in the soils.
