Sugarcane Bagasse Ash

Industrial wastewater containing toxic pollutants such as heavy metals tends to contaminate the environment once it is release without proper treatment. Heavy metals are toxic to both human and other living organisms. It is necessary to treat industrial wastewater polluted with heavy metals prior to its discharge into the receiving environment. In this study, low cost adsorbent was generated from sugarcane bagasse through incineration. The prepared adsorbent “microwave incinerated sugarcane bagasse ash” (MISCBA) was used in removing copper and zinc from aqueous solution. Parameters of importance such as pH, contact time and adsorbent dosages are studied to investigate their effects on the adsorption of copper and zinc. Maximum adsorption was observed at pH 6.0, contact time of 180 minutes and adsorbent dosage of 10 g/L. Zinc removal follows Langmuir isotherm model with correlation coefficient of 0.9291. Copper adsorption follows both Langmuir and Freundlich isotherm model with correlation coefficient of 0.9181 and 0.9742, respectively. Removal capacities of 38.4 mg/g and 20.4 mg/g were obtained for copper and zinc, respectively. Application of MISCBA as low - cost adsorbent have shown significant outcome in removal of copper and zinc from aqueous solution.

Effective Sorbent

Characteristics and efficiency of wasted black tea (WBT) were investigated as a low-cost sorbent in removal of Ni2+and Zn2+ions from aqueous solution. Initial findings showed WBT potential to be applied as an effective sorbent due to high concentrations of carbon and calcium and high porosity and availability of functional groups. Sorption dynamics were studied with varying pH, contact time, and adsorbent dose. Maximum percentages of metal ions removal were recorded at pH 5, contact time 250 min, and 20 g/L of adsorbent concentration. Binary metal sorption studies showed that Ni2+and Zn2+do not compete with each other for available sorption sites, so the adsorption trend in binary system appears similar to monocomponent metal adsorption. Evaluation of the isotherms confirmed that WBT has high value of adsorption capacity. Sorption data fitted well with both Freundlich and Langmuir models. In the optimum conditions, maximum capacity of WBT could reach up to 90.91 mg-Ni/g adsorbent and 166.67 mg-Zn/g adsorbent. This experiment demonstrated the ability of tea waste as an effective, sustainable, and low-cost adsorbent for removal of the heavy metal ions.
