Management of Solid Waste Containing Fluoride—A Review

Technological and economic development have influenced the amount of post-production waste. Post-industrial waste, generated in the most considerable amount, includes, among others, waste related to the mining, metallurgical, and energy industries. Various non-hazardous or hazardous wastes can be used to produce new construction materials after the “solidification/stabilization” processes. They can be used as admixtures or raw materials. However, the production of construction materials from various non-hazardous or hazardous waste materials is still very limited. In our opinion, special attention should be paid to waste containing fluoride, and the reuse of solid waste containing fluoride is a high priority today. Fluoride is one of the few trace elements that has received much attention due to its harmful effects on the environment and human and animal health. In addition to natural sources, industry, which discharges wastewater containing F− ions into surface waters, also increases fluoride concentration in waters and pollutes the environment. Therefore, developing effective and robust technologies to remove fluoride excess from the aquatic environment is becoming extremely important. This review aims to cover a wide variety of procedures that have been used to remove fluoride from drinking water and industrial wastewater. In addition, the ability to absorb fluoride, among others, by industrial by-products, agricultural waste, and biomass materials were reviewed.

We have deposited nitrogen-doped diamond-like carbon (N-DLC) films by plasma-enhanced chemical vapor deposition using CH 4 , N 2 , and Ar, and investigated the effects of N doping on the structure and the electrical, mechanical, and optical properties of the N-DLC films. We fabricated undoped DLC/p-type Si and N-DLC/p-type Si heterojunctions and examined the current-voltage characteristics of the heterojunctions. When the N 2 flow ratio was increased from 0 to 3.64%, the resistivity markedly decreased from the order of 10 5 Ω&cm to that of 10 %2 Ω&cm and the internal stress also decreased. The resistivity gradually increased with increasing N 2 flow ratio from 3.64 to 13.6%, and then it decreased at a N 2 flow ratio of 13.6%. These behaviors can be explained in terms of the clustering of sp 2 carbons and the formation of sp 3 C-N, sp 2 C=N, sp 1 C¸N, and C-H n bonds. The rectification ratio of the heterojunction using the N-DLC film prepared at 3.64% was 35.8 at +0.5 V.

“…Carbon-based solar cells have been successfully made using SWCVD with an acetylene source and trimethyl boron as a doping source for a p-type layer. The samples were deposited on an n-type silicon substrate in two p-C/n-Si and p-C/i-C/n-Si configurations [23]. Using rf-PECVD, a solar cell with the p-PAC/i-a-Si:H/n-Si:H configurations has been successfully fabricated [24].…”

“…Amorphous carbon homojunction solar cells have not yet been developed by previous researchers. The main source of doping in the development of solar cells are gaseous doping sources [12,13,23,25,26], and liquid doping sources have never been used. The main source of carbon as active material is dominated by hydrocarbon compounds, and the use of carbon derived from agricultural products (biomass) has not been significantly developed.…”

An a-C/a-C:N junction, which used palmyra sugar as the carbon source and ammonium hydroxide (NH 4 OH) as the dopant source, was successfully deposited on the ITO glass substrate using the nano-spraying method. The current-voltage relationship of the junction was found to be a Schottky-like contact, and therefore the junction shows the characteristic rectifiers. This means the a-C and a-C:N are semiconductors with different types of conduction. Moreover, the samples showed an increase in current and voltage value when exposed to visible light (bright state) compared to the dark condition, thereby, indicating the creation of electron-hole pairs during the exposure. It was also discovered that the relationship between current and voltage for the a-C/a-C:N junction sample formed a curve that satisfies the rule of the photovoltaic effect when exposed to visible light from a light bulb. The exposure of this sample to direct sunlight at AM 1.5 conditions produced a curve that meets the rules for the emergence of the photovoltaic effect with higher characteristics for the current-voltage relationship. Thus, the a-C/a-C:N junction sample is a solar cell successfully fabricated using a sample method and has a maximum efficiency of 0.0013%.
