Biosorption is an efficient and cost effective method for heavy metals remediation. However, saturated biosorbents may present a serious problem for the environment. Flax fibers have previously shown very good adsorption capacities to remove zinc, co

The clogging caused by the deposition of suspended particles modifies in depth several mechanical parameters (permeability, porosity, bulk moduli, etc.) of porous media and influences the acoustic behaviour. Consequently, at a fixed position in the m

Competitive and non-competitive batch experiments were conducted on flax fibers to study Zn2+, Cu2+, and Pb2+ ions biosorption performance. Biosorption efficiency was dependent on contact time, pH, and biosorbent concentration. The results under comp
