Waste Reduction By Prcipitation
Introduction
The solution being used (sodium phosphate, sodium carbonate, potassium chromate, or calcium hydroxide)and the copper (II) chloride waste are placed in a mixing apparatus. When the mixture has been thoroughly combined, it is transported to the filtration system. Water is run through the mixing apparatus to remove any remaing precipitate and transport it to the filtration system. Here, the precipitate and the filtrate are separated. We test the filtrate using ammonia to find approximately how many ppm of toxic waste still remain. A simulation of acid rain was conducted and tested to find the presence of the Copper (II) Chloride in the waste. The procedure is completed with all four chemical solutions to discover which precipitate best retains Copper (II) Chloride waste.
One advantage to ths method is that ultimately, the Copper (II) Chloride solution will not harm the environment and it will not take up too much space at the landfill site. This will profit the environment as well. It does not require a large work force and the process is simple. In addition, the monthly cost is kept relatively low with the money made by selling the potassium chloride. On the other hand, this method has several disadvantages. The initial start up cost is extremely high because a mass spectrometer is ncessary to accutately determine the level of waste present. Also, although the potassium chromate is properly stored in barrels, it could leak if not properly stored in the landfill.
The objective of this method is to reduce the toxic Copper (II) Chloride waste in a way that is effective for our company and safe for the environment. This is done when a double replacement reaction occurs and the copper bonds with the negative part of the solution added to form the precipitate.
