چکیده مقاله:

This study illustrates the process of removal of chromium from chrome tanning waste-water by fly ash which was drive from chrome shaving dust. This experiment was carried out in a batch process with laboratory preparedadsorbent samples and chrome tanning water collected from local tanneries. The influence of various factors likes adsorbent doses, contact time, and initial concentration of chromium on the removal of chromium from effluent was investigated. FTIR analysis was done to identify the functional groups presents in the fly ash. The maximum removal of chromium and absorption capacity was found to be 97.86%. And 23.11 mg/g at chromium concentration of 1000.3mg/ l and 1291 mg/l respectively. Total dissolve solid, turbidity, and conductivity were reduced significantly. Waste water samples containing several interfering ions like Na, Fe, Ca, Zn, Mn etc. The langmuir absorption isotherm was also used to explain the nature of adsorption. This result indicates that chrome shaving dust ash can be successfully used to treat chrome tanning wastewater.
