Determination of total organic carbon in karst groundwater by ultraviolet oxidation technology (CAT#: STEM-PPA-0137-LJX)

Introduction

Karst groundwater, also known as karst water, refers to the water in the dissolution cracks and caves of soluble rock formations, and its most obvious feature is that the distribution is very uneven. Karst water-bearing systems are generally rich in water and good in water quality, and are often used as large and medium-sized water sources.
Total organic carbon (TOC) is an important carbon component in the global carbon cycle and the primary food source of the aquatic food chain. Therefore, the measurement of TOC plays an important role in the analysis of carbon flux in aquatic systems and the study of the global carbon cycle. The determination of total organic carbon in karst groundwater is helpful to evaluate the role of organic matter in the global carbon cycle.
