“…Sunflower husk was used as biosorbent for removing cationic dyes (Soldatkina et al 2009) and various heavy metals Witek-Krowiak 2012). But scarce information about its use as a biochar for wastewater decontamination Tikhonova et al 2008) is available. Therefore, the principal objective of this study was to investigate the ability of sunflower seed husk biochar (SSHB) to remove copper ions from aqueous solutions.…”

Saleh M.E., El-Refaey A.A., Mahmoud A.H. (2016): Effectiveness of sunflower seed husk biochar for removing copper ions from wastewater: a comparative study. Soil & Water Res., 11: 53-63.Copper represents one of major hazardous pollutants in wastewater. The aim of this study is the comparison between sunflower seed husk biochar (SSHB) and activated carbon (AC) and sunflower seed husk feedstock (SSHF) in their efficiency of Cu 2+ removing from aqueous solutions. The removed Cu 2+ was monitored for various intervals extended to 96 h at 298, 303, and 308 K in batch experiments. Adsorption reactions showed that SSHB was superior in Cu 2+ removal process at all tested temperatures in comparison with AC and SSHF. Results of surface properties and Fourier transform infrared spectroscopy confirmed the higher surface reactivity of SSHB than AC and SSHF. Both SSHF and AC were affected by time and temperature of reaction in their removal efficiency for Cu 2+ while SSHB was not affected by these parameters. A deformation observable under a scanning electron microscope and a higher release of dissolved organic carbon from SSHF after the reaction with Cu 2+ and vice versa in SSHB suggested the electrostatic ion exchange and complex reactions mechanisms for Cu 2+ removal by SSHF in addition to the physical sorption controlled by surface area and porosity of SSHB. The adsorption kinetics of Cu 2+ was fitted to pseudo second order equation and obtained results indicate that SSHB is a recalcitrant and a strong biosorbent. Therefore, SSHB can be introduced as a cost-effective and efficient biosorbent for copper removal from wastewaters.

“…The detrimental effect of organic suspensions on the process of self-purification of waters lies in the sediments with which they cover the bottom and delay or completely stop the vital activity of microorganisms. As they are able to selectively act on various wastewater containing suspensions of organic origin and thus regulate the dissolved organic matter, they negatively affect the state of water bodies [22][23][24]. Such a mechanism makes it difficult for light to penetrate to depth and hinders the processes of photosynthesis.…”

This study aims to explore the potential of new microorganisms for bio-purification of polluted reservoirs in Northern Kazakhstan. Through laboratory experiments involving field collection of hydrobiological samples and screening of new strains of microorganisms, the study suggests that biological purification using organic and inorganic compounds found in polluted waters as a nutrient medium is the most effective method. This research contributes to the development of effective strategies for addressing pollution in Northern Kazakhstan's water resources and highlights the potential of using microorganisms as a tool for environmental remediation. The significance of the research lies in the fact that it proposes a solution to the issue of pollution in reservoirs in Northern Kazakhstan through the introduction of new strains of microorganisms, contributing to the development of effective strategies for improving water quality and minimizing the negative impact of pollutants on the hydrosphere.
