Discharging industrial colored wastewaters into aqueous
environments can cause adverse effects on aquatic life due to the
toxic nature of synthetic dyes. The present study aimed to evaluate
the efficiency of using cryptocrystalline magnesite to remove an
anionic dye (Methyl Orange - MO) from aqueous systems. To
achieve that, several operational factors like residence time,
adsorbent dosage, species concentration and temperature were
appraised. The batch study proved that cryptocrystalline magnesite
is effective in the treatment of MO contaminated water and
moreover it performed well in terms of color removal. The removal
efficiency of cryptocrystalline magnesite was found to be 85.85%
for 30 mg/L of MO solution
