undertaken to develop a cost effective biosorbent and to study the biosorption process involved in the adsorption of heavy metal-contaminated industrial wastewater using the developed biosorbent. Coconut shell carbon was modified with chitosan and/or oxidizing agent (phosphoric acid) to produce composite adsorbent. The adsorption efficiency of the adsorbent was evaluated by measuring the extent of adsorption of zinc (II) in synthetic beverage industrial wastewater. Operational parameters such as pH‚ agitation

ADSORPTION AND ABSORPTION OF EXHAUST GASES FROM VEHICLES Rinkesh.A.Bafna‚ Kushal.A.Khanderia‚ Asst.Prof. N.Anandakumar Abstract— As India is developing in a faster rate the need for vehicles has tremendously increased. In this scenario‚ we strongly need an efficient way to control the increasing air pollution led by the exhaust gases from the vehicles. These exhaust gases contains carbon monoxide (CO) and hydrocarbons in high proportions which adversely increases the Global Warming and

3.3 Results and Discussion 3.3.1 Particle Size of Asphaltenes. DLS was utilized to obtain the hydrodynamic radius of asphaltenes in toluene‚ which could help understand the behaviors of asphaltenes in the bulk solutions and oil/water interfaces. Figure 1 shows the particle size distribution of asphaltenes under different concentrations at 23 ℃ and under 2000 mg/L at different temperatures. A summary of the average particle size under different concentration and temperature conditions is shown in

company that primarily manufactures stable bleaching powder. It should be noted that stable bleaching powder could be manufactured through two different techniques: adsorption or absorption. By using adsorption‚ this means that BBC’s product was of an inferior quality compared to the products of its competitors. However‚ the use of adsorption allowed the company to enjoy a favorable market share‚ and due to the cost advantage‚ BBC was able to pass on lower prices to its customers. Currently‚ BBC is contemplating
