Abstract: Pollutants, particularly harmful heavy metals, are released into the environment, posing serious health risks to humans and other living species. The human body does not require lead, which is a toxic chemical. As a result, in order to eradicate or remove lead from the environment, a range of technologies must be used. The goal of this research was to use low-cost, high-efficiency adsorbent materials to adsorb lead (II) ions from aqueous solutions. Adsorption capacity, elimination percent, and batch adsorption settings are all discussed in this work. The adsorption capacity and percentage removal of lead from aqueous solutions by adsorption are affected by the initial concentration, pH, adsorbent dose, contact time, and temperature. The goal of this research was to use low-cost, high-efficiency adsorbent materials to adsorb lead (II) ions from aqueous solutions. The impacts of several parameters on the adsorption process such as pH, contact time, initial concentration of lead (II) ions, and temperature were examined. Therefore, lead (II) ions can be removed from the water body effectively using low-cost adsorbent materials.

Abstract: Welding of dissimilar steel and TiNi shape memory alloys, aluminum alloy, magnesium alloy and other metals is an important issue because of its increasing applications in industries. This review aimed to provide a comprehensive overview of the recent progress in welding and joining of steel and heterogeneous metals and to introduce current research and application. However, the base materials on both sides of the traditional fusion welding must melt and the large melting point difference between the two seriously affects the weld formation. The metal compounds formed by the base materials on both sides also hinder the improvement of the mechanical properties of the joint. The methods available for welding steel and dissimilar metals included fusion welding, brazing, diffusion bonding, friction welding and reactive joining. The current state of the understanding and development of fusion welding method for steel and other metals was addressed. This review focused on the fundamental understanding of the microstructural characteristics, processing and property relationships in the welding and joining of heterogeneous joints.
