Changes in degraded peat land characteristic using FTIR-spectrocopy

Abstract

Degraded peatlands can be detected laboratory analysis and field appearance. Peatlands degradation is characterized by a very reduced water holding capacity which is caused by peat fire or over drain. The capacity of peat to hold water is closely related to their functional groups. Analysis using Fourier Tansform Infrared (FTIR) Spectrocopy enable to determine the functional groups of peat. The research was aimed to study peatland degradation based on functional group changes through FTIR analysis. The samples of peat soil were taken from burned peatland, agricultural peat land and natural peat in Kalampangan, Central Kalimantan. The hydrophobic properties of the functional group are indicated as lignin, carboxylic or phenolic groups, fat, wax or lipids, while the hydrophilic functional group is indicated as protein and cellulose. Degraded peat have the hydrophobic group of 56.20%, while in natural peatlands was around 29%. Hydrophilic functional group on burned peatlands was 34.5-43%, natural peatland was 60-70% and agricultural peatland was 66%. Functional group analysis using FTIR can be used to detect the level of peatland degradation, through a significant increase in hydrophobic groups

Mapping the Restoration of Degraded Peatland as a Field of Research Area: A Scientometric Review

“…Soil pH in degraded peatlands is 3.62, whereas in agricultural soils it is 4.70 (Maftu'ah et al, 2019). According to (Maftu'ah et al, 2019), the overall pH of soil differed signi cantly.…”

“…Soil pH in degraded peatlands is 3.62, whereas in agricultural soils it is 4.70 (Maftu'ah et al, 2019). According to (Maftu'ah et al, 2019), the overall pH of soil differed signi cantly. Ion H + and Al 3+ were the main sources of the low pH in the peat in the examined area (Maftu'ah et al, 2019).…”

“…Soil hydrophobicity can aid in evaluating soil quality and fertility factors (Matejková et al, 2012). According to (Maftu'ah et al, 2019), soil water content at the study site showed a substantial variation. Compared to natural peatlands and agricultural land, there was a considerable decrease in water content in degraded peatlands, reaching more than 3 times lower.…”

“…The impact of peatlands that have been degraded or disturbed has changed in physical characteristics, biology, and chemistry, resulting in a loss of the ecological function of the peat, putting environmental and social-economic development at risk (Maftu'ah et al, 2019). Some of the repercussions of disturbing peatland include hydrophobicity, increased soil acidity, and decreased total organic carbon (TOC) and total organic nitrogen (TON) (Anshari 2010).…”

A Thermal Study on Peat Oxidation Behavior in the Presence of an Iron-Based Catalyst

“…Peat is used in different sectors, such as medium-scale combined heat and power plants, which generate electricity and heat for industrial processes [15][16][17]. Moreover, peat represents a potential source of hydrocarbons that can be extracted by applying methods to enhance oil recovery.…”
