description |
Batik home industry occurs wide spread in Yogyakarta City, which
produce a large amount of waste water with contain high contaminant such as
copper (Cu). Although Cu is an essential element for daily consumption, when
Cu becomes abundant in soil side effects can occur. Hence, groundwater
vulnerability for Cu must be applied in order to screen the sensitivity of an
aquifer to being adversely. In previous study, it was reported that only few
methods can assess specific groundwater. However, there is no report on the
relationship between groundwater vulnerability and chemical reaction factor for
Cu. Therefore, new chemical reaction factor was created to modify simple
vertical vulnerability (SVV) method for Cu.
In this context, the objective of this study is to modified SVV method by
chemical reaction factor that related to Cu sorption capacity of unsaturated soil.
The sorption capacity of the unsaturated soil for Cu is evaluated by using batch
experiments. In addition, XRD, XRF and chemical extraction, and sequential
extraction experiments were determined mineralogy, chemical composition and
the dominant form of Cu in the soils. Using data from sequential extraction
experiments, geochemical modeling could figure out distribution of Cu in the
study area.
XRF, chemical extraction and sequential extraction results show that
plagioclase feldspar is main mineral contain in every soil type at the study area
with small amount of kaolinite and ferrihydrite found in clay fraction. Chemical
composition is dominant by SiO2, Al2O3, CaO, and Fe2O average concentration
are 56.30 wt.%, 21.60 wt.%, 8.03wt.%, and 6.99 wt. % respectively. The
sequential extraction determined the dominant form of Cu in the soil as
(1)soluble ion, (2) exchangeable, (3) bound to amorphous, poor crystalline iron
and aluminum minerals, (4) bound to iron minerals, or (5) bound to clay mineral.
The Cu sorption is mainly influenced by iron amorphous phase and Cu
concentration detected in this phase is 65-86.4%.
The batch experiments were performed for four types of soil using
artificial Cu solution (0.01, 0.1, 1, and 10 mmol/L), with same adsorbent of
10g/L. The result showed that the lower the initial concentration of Cu solution,
the better the Cu adsorption capacity. The solution of 0.01mmol/L has the best
adsorption capacity with 98-99%.The sorption capacity of soil in the study area is
related to ferrihydrite and kaolinite content in clay fraction. The higher the clay
fraction content, the higher the Cu sorption capacity. The high clay fraction
content is observed in loamy fine sand (6.61%) and fine sandy loam (4.69%),
while lower clay content characterizes in sandy loam (2.78%) and sand (1.89%).
Surface complexation model were performed by using ferrihydrite and
kaolinite content in clay fraction based on the results of XRF, chemical
extraction, sequential extraction and batch sorption experiments. Moreover, the
input data was based on secondary data and duplicated from batch sorption
experiment condition. The result shows that Cu adsorption to ferrihydrite is
higher than kaolinite, about 200 times in low initial concentration (Cu 0.01
mmol) and 6-9 times in high initial concentration (Cu 0.1 and 1mmol). This
modeling result agrees with the result of sequential extraction, indicating the
sorption capacity was affected by both ferrihydrite and kaolinite in clay fraction,
however ferrihydrite is main mineral for Cu sorption.
Based on the result of sequential extraction, batch sorption experiment
and geochemical modeling, the chemical reaction factor was assigned base on
clay fraction because ferrihydrite and kaolinite is main component of clay
fraction. Moreover, the SVV_Cu method derived by combine chemical reaction
factor with soil parameter. The result of SVV_Cu method show that the study
area is moderate, low and very low groundwater vulnerability, this indicates that
groundwater at the study area is moderate, high and very high protection. At site
condition, the groundwater quality, Cu is low concentration which refers to good
protection. This result agrees with SVV_Cu method that the study area has high
protection of groundwater, indicating SVV_Cu method is appropriate for Cu. |
