CLEAN – Soil, Air, Water

Effects of salt stress, water table, and their combination on growth, chlorophyll content, antioxidant system, and ion accumulation in Suaeda salsa plant were studied. The results indicated that S. salsa could adapt to the adverse soil environments through modifying their growth and physiology status.

The electrokinetic process to restore sulfate-accumulated saline soil and to reduce soil EC was used by applying a longer treatment duration. After the electrokinetic process, the 16-day experiment met the EC guideline value (2.0 dS/m). These experimental results suggest that this process is a promising technology.

A combination of Fourier transform IR attenuated total reflectance (FTIR-ATR) and synchrotron FTIR techniques were applied to the investigation of sediments and related materials. The FTIR techniques give information on the functional groups of the compounds found in the sediments.

The BIOREGIS experimental software platform described in this paper is an attempt to build an information tool able to manage petroleum contaminated sites and to support the planning, monitoring, archiving of remediation activities.

This study investigated the equilibrium and the dynamics of the adsorption of the pesticides monocrotophos and dichlorvos on three different soils. The higher adsorption of MCP and DDVP on sandy soil indicates a mobility with potential to leach and eventually pollute ground and surface water.

The results of this study provide valuable information suggests that physicians should help their patients select drinking water that contains the mineral content, i.e., most appropriate to their individual dietary needs.

Multiwalled carbon nanotubes were used as a solid adsorbent for selective separation/preconcentration of silver(I) at ng L⁻¹ levels in water. The advantages of the present SPE method are the simplicity, speediness, and the economic aspect.

This study concentrates on the possible application of the spent cottonseed husk substrate, an agricultural waste used after the cultivation of white rot fungus Flammulina velutipes, to adsorb methylene blue (MB) from aqueous solutions.

DLLME-SFO combined with FAAS was evaluated for the preconcentration and determination of the trace lead content (at µg L⁻¹ levels) from water. The precision and accuracy of the method was satisfactory.

The efficiencies of phosphorus and nitrogen removal and the recovery by struvite precipitation and air stripping were investigated. The results suggest that struvite precipitation is a highly efficient method for removing phosphorus from diluted and undiluted urine. In both cases, PO₄-P-removal efficiencies of 98% could be achieved.

This review summarizes the pesticide removal through both conventional and biosorption methods, and the factors affecting them, isotherms, the thermodynamic and kinetic, and mechanisms of the biosorption process.

Rhodamine B was loaded onto Amberlite IR-120 to produce a new sorbent for separating heavy metals. The results indicate that the modified material can be successfully used for the analysis of synthetic as well as real samples (electroplating wastewater).
