1. GREEN CHEMISTRY in LAB Quiz and Discussion Green Chemical Analysis Green of Analytical Chemistry Application of the principles of green chemistry in analytical chemistry

2. Analytical Chemistry The main role of analytical chemistry is to be a controlling tool or set of tools in chemistry. As a tool, the analytical procedures give information about chemical substances, their occurrence in organisms, and the environment. It has supported the development of chemical engineering and technology for production of chemicals. The product life-cycle analysis is impossible without the chemical analysis of components and degradation products. The development of the standards and specifications to be used in industry and agriculture is strongly based on the evidence obtained by analytical chemistry and controlled by chemical methods. Analytical chemistry is the only way to justify the environmental friendliness of new methods, processes, and products.

4. Green Chemical Analysis The relationship between green chemistry and analytical chemistry can be treated in two ways : Analytical chemistry is a subject to control and justify green chemistry. Analytical chemistry becomes an object of application of the principles of green chemistry, and can be the target of a green chemistry approach similarly to other areas of chemistry and chemical technology.

5. Quis 1: Lengkapi pernyataan berikut : Hubungan kimia analitik dengan green chemistry, ada 2: Kimia analitik sebagai ……………….. pengontrol dan penentu green atau tidak green. Kimia analitik sebagai ………… dari aplikasi prinsip green chemistry.

6. Green Chemical Analysis The relationship between green chemistry and analytical chemistry can be treated in two ways : Analytical chemistry is a subject to control and justify green chemistry. Kimia analitik berperan menjustify apakah produk kimia atau teknologi kimia hijau atau tidak Analytical chemistry becomes an object of application of the principles of green chemistry, and can be the target of a green chemistry approach similarly to other areas of chemistry and chemical technology. On the other hand, chemical analysis methods need solvents, reagents, and energy, and they generate waste  memenuhi prinsip green chemistry ? Dalam aktivitas analisis kimia juga harus diterapkan prinsip-prinsip green chemistry

13. Green chemical analysis What is green analytical chemistry? The goal of green analytical chemistry is to use analytical procedures that generate less hazardous waste and that are safer to use and more benign to the environment. The main analytical result is related to an increase of analysis reliability, higher precision, and time saving, which very positively combines with a substantial reduction of waste.
