초록/요약
Potentiometric Titration was utilized in this research as an effective method to derive point of zero charge of glass and PVC which has posed threat to the environment and human when disposed and distributed in nature as a method of incineration or landfill. Since the point of zero charge of glass and PVC was presented in the opposite end of the range from pH 2 to pH 12, respectively pH 2.1 and pH 11.7, it was concluded that glass would be mostly positively charged in aqueous solution while PVC would behave the opposite. Therefore, the conclusion could be used as the basic study for preparation of pure sample that is crucial in provision of recycled product with superior quality, which can achieve not only economic benefits and eco-friendliness but also sturdy materials to be used in industries and daily lives. As an effort for deriving a flowchart of purification, flocculation and dispersion was applied while considering the relation between point of zero charge and surface charge in this research. In other words, the analysis of point of zero charge of particulate matters could lead to the possibility of separating them in colloidal state by converting pH of solution and improving the condition of recycled outputs.
