Marine Macroalgae Bio-adsorbent for Water Treatment: Trichlorophenol Removal

Date        : Thursday, Feb 06, 2020

Time       : 2:00 – 2:30 PM

Location  : Building 15, 4th floor Auditorium

Abstract:

        Certain water contaminants are potentially bio-accumulative, toxic and carcinogenic. They present great concern if released into the environment. Among the available water treatment technologies, adsorption has proven to be excellent with many advantages over other techniques. Some of these advantages are availability, ease of handling, and high efficiency. However, biosorption using naturally available macroalgae has been proven to produce promising results in removing pollutants, such as heavy metals and organic contaminants. Due to its natural availability and hence, low cost, biosorption via macroalgae has become a viable alternative for the efficient removal of pollutants from water. The resulted biochar from the thermal pyrolysis of Sargassume Bovenoum Macroalgae was used for the removal of Trichlorophenol (TCP). TCP is one of the main contaminants discharged from refineries, paper industry and other sources. The effects of adsorption parameters (adsorbent dose, pH, adsorbate concentration, contact time and temperature) were investigated in this research, as well. The results showed that the adsorption capacity of Sargassume Bovenoum for TCP before treatment was relatively low. However, after thermal pyrolysis, it was significantly improved. It has the capability to remove 100 % of TCP from distilled water and around 60 % from high saline seawater.
