Tóm tắt

Đá chứa một lượng lớn các nguyên tố như Na, K, Ca, Mg, Fe, Mn và Ti. Việc xác định hàm lượng các nguyên tố trong đá có ý nghĩa quan trọng trong thăm dò địa chất, địa lý cũng như xác định nguồn gốc và phân loại đá. Hiện nay việc phân tích thành phần các nguyên tố trong đá có thể được tiến hành trên các thiết bị như ICP-OES, ICP-MS,... Tuy nhiên, ở một số phòng thí nghiệm có điều kiện hạn chế thì việc phân tích này gặp nhiều khó khăn. Trong nghiên cứu này chúng tôi tiến hành phân tích các mẫu đá sau khi đã được xử lý bằng vi sóng bằng phương pháp phổ hấp thu nguyên tử ngọn lửa và phổ hấp thu phân tử UV-vis. Kết quả phân tích cho thấy hàm lượng các nguyên tố trong khoảng Na (0.31 – 2.46%), K (1.38 – 3.71%), Ca (0.08 – 0.23%), Mg(0.16 – 0.69%), Fe(2.38 – 5.19%), Mn(0.08 – 0.1%) và Ti(0.12 – 0.36%). Nghiên cứu này cung cấp phương pháp phân tích đơn giản, giá thành thấp phục vụ nghiên cứu thành phần của đá

Quang Huy Le, Nguyen Tat Thanh University, Ho Chi Minh City, Vietnam

Le Quang-Huy received the B.S degree in chemistry from University of Science, Vietnam National University Ho Chi Minh city in 2021. He is currently pursuing the M.S. degree in chemistry at University of Science, Vietnam National University Ho Chi Minh city.

He is working as a Technician at Nguyen Tat Thanh University. His research interests include the development the methods to determine the metals in foods samples, materials and environmental. He also works on environmental quality assessment.

Thanh Nho Nguyen, Nguyen Tat Thanh University, Ho Chi Minh City, Vietnam

Nguyen Thanh-Nho currently acts as a lecturer and researcher. He is specialist in Environmental Chemistry and Toxicology. He obtained a PhD. in Earth Science at University of New Caledonia (France) in 2018. He hold a Degree of Master in Analytical Chemistry from University of Science – Vietnam National University Ho Chi Minh City in 2013. Dr. Nguyen Thanh-Nho has worked many years on the analysis and risk assessment of trace metal(oid)s in food, medicinal, agricultural products, and other contaminants.

He has a broad insight and interest in the identification, fate and health relevance of water and sediment pollutants, i.e. biogeochemistry of trace elements, their nutritional relationships in tropical ecosystem, especially (e.g. mollusk, crab, fish, snail, various types of trees) and questions relating to sedimentary processes in coastal area. He also serves as an advisor on environmental issues and analytical processes to various organizations such as center of environmental analytical service, companies supplying analytical instruments. With the strong knowledge and experience on the environmental chemistry and analytical chemistry, his studies are going on the quality of soil, sediment and water applied for agricultural cultivation as well as on the bioavailability of trace elements and their bioaccumulation into plant and animals tissues that can be a potential risk to human health.
