“…Water contamination is one of the most important and high priority research topics around the world, as the availability of clean water is not only essential for life but it is also of paramount importance for social and economic development [ 1 ]. Unfortunately, as agricultural, industrial, and urban activities flourish, the pollution level in the environment and particularly in water bodies also increases [ 2 , 3 ]. Organic matter, nutrients, fertilizers, pesticides, dyes, pharmaceuticals, personal care products, oils, and heavy metals can be counted among the commonly found contaminants [ 4 ].…”

Contamination of water by heavy metals is a major environmental concern due to the potential ecological impact on human health and aquatic ecosystems. In this work, we studied the chemical modification of various fruit peels such as banana (BP), granadilla (GP), and orange ones (OP) in order to obtain novel bio-adsorbents to improve the removal of Zn(II) ions from 50 mg·L−1 synthetic aqueous solutions. For this purpose, sodium hydroxide and calcium acetate were employed to modify the fruit peels. The moisture, extractives, lignin, hemicellulose, and cellulose contents of the raw materials were determined according to ASTM standards. The obtained bio-adsorbents were characterized by scanning electron microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR) and thermogravimetric analysis (TGA). The results showed the OP bio-adsorbents performed better, especially when the concentration of the modifier solutions increased, e.g., the OP particles modified using 0.8 M NaOH and Ca(CH3COO)2 solutions resulted in 97% removal of Zn(II) contaminating ions and reached a maximum adsorption capacity of 27.5 mg Zn per gram of bio-adsorbent. The adsorption processes were found to follow a pseudo-second order model. The error function sum of square error indicated the Freundlich isotherm (non-linear regression) as best fit model. The obtained results are particularly interesting for material selection in wastewater treatment technologies based on contaminant adsorption.

“…Hasil penelitian Silva et al (2017) menunjukkan bahwa logam berat Pb memiliki bioavaibilitas paling rendah dibanding dengan logam lain seperti Zn, Cr, Cu dan Cd, sehingga potensi akumulasi dalam sedimen lebih besar. Beberapa penelitian lain juga dilakukan untuk mengukur tingkat pencemaran logam berat dalam sedimen (Ghrefat and Yusuf, 2006;Khaled et al, 2006;Chen et al, 2007;Cevik et al, 2009;Vukovic et al, 2011;Permanawati et al, 2016;Bhuyan et al, 2017;Xu et al, 2017;Chen et al, 2019;Cui et al, 2019;Hoang et al, 2020;Islam et al, 2020).…”

The water and sediment caused by heavy metal has become a major problem in coastal areas. Heavy metals released into the water binds to particulate matter, accumulate into sediments and its predicted by the pollution assessment method. The aims of this research was to investigate the distribution and contamination levels of Pb in water and sediments of Bondet Estuary. Water and sediments samples were collected from four stations in September 2020. The monitoring data of water quality status, contamination factor (CF), and geo-accumulation index (Igeo) were used to provide a assessment of the Pb contamination. The concentration of Pb in water at all stations (0,024-0,031 mg/L) was higher than the standard surface water, with the status is lightly polluted (class B). CF index for all stations 1 ≤ CF <3 indicates moderate Pb contamination in the sediment, while Igeo for each station is <0, which means no contamination. Overall when referring to some guidelines for sediment standards, Pb concentrations at all stations were still below the standard value for sediment. This study provides a basis for assessing future conditions and risks, so that it can contribute to the management and evaluation of heavy metal contamination in the Bondet Estuary.

“…In the face of technological and industrial advances, there was an increase in consumption and brought about an increase in production, this activity is of great importance for the growth of the country's economy but must be accompanied by plans to mitigate environmental impacts and solid environmental recovery, which promote the benefit of both the population and the environment (3). But in recent years this has not happened, some large companies have brought great harm to the environment due to the lack of maintenance of their production systems and environmental emergency measures.…”

Due to several catastrophic fires in France involving flammable organic plastics, Davidovits began his search for new materials resistant to heat, developing an alkaline activated silico-aluminous material, which was called a geopolymer. The polymeric Si-O-Al network gives the geopolymer ion exchange property, allowing the immobilization of heavy and radioactive metals within the material matrix. Due to the geopolymer's characteristic of immobilizing heavy metals in its matrix, this project aims to evaluate the geopolymer's ability to absorb heavy metals in contaminated water. For this, samples of porous geopolymers with magnetic charges in concentrations of 1, 2 and 3% were produced. And, subsequently, toxic metal solutions were made, such as Chromium, Cadmium and Lead at a concentration of 3ppm, then the sorption was carried out using the static method, where 0.5 g of the gepopolymer was dispersed in 25 ml of contaminated water and left stirring for 5 minutes, with the aid of a mechanical stirrer, and left to rest for 24 hours for the geopolymer to settle and the supernatant to be collected (this procedure was performed for geopolymers with and without magnetic charges). Afterwards, the treated water was analyzed by the atomic absorption technique, in order to investigate the geopolymer's sorption capacity. All tests were performed in triplicate and the mean, standard deviation and 95% confidence limit were evaluated to determine the reliability of the results.
