The primary, most obvious parameter indicating water quality is the color of the water. Not only can it be aesthetically disturbing, but it can also be an indicator of contamination. Clean, high-quality water is a valuable, essential asset. Of the available technologies for removing dyes, adsorption is the most used method due to its ease of use, cost-effectiveness, and high efficiency. The adsorption process is influenced by several parameters, which are the basis of all laboratories researching the optimum conditions. The main objective of this review is to provide up-to-date information on the most studied influencing factors. The effects of initial dye concentration, pH, adsorbent dosage, particle size and temperature are illustrated through examples from the last five years (2017–2021) of research. Moreover, general trends are drawn based on these findings. The removal time ranged from 5 min to 36 h (E = 100% was achieved within 5–60 min). In addition, nearly 80% efficiency can be achieved with just 0.05 g of adsorbent. It is important to reduce adsorbent particle size (with Φ decrease E = 8–99%). Among the dyes analyzed in this paper, Methylene Blue, Congo Red, Malachite Green, Crystal Violet were the most frequently studied. Our conclusions are based on previously published literature.

“…Abioye et al, [21] reported that melon shells have the potential of degrading the crude oil content in crude oil contaminated soils by about 75% within a 28-day experimental period. According to Aslam and Ayush [22], charcoal powder is an efficient adsorbent, absorbing about 99 % crude oil from crude oil contaminated seawater. Vasilyeva et al [23] reported that activated carbon is a good adsorbent for organic contaminants; probably due to its hydrophobicity and microporous structural makeup.…”

The adsorption of Total Hydrocarbon Content (THC) from petroleum products contaminated soil using wood charcoal blocks and sawdust was investigated in this study. 130kg of the sieved topsoil was contaminated with 5L of spent motor engine oil, 5L of kerosene, 5L of petrol and 5L of diesel, and left to stabilize for two weeks; after which it was thoroughly mixed together. The thoroughly mixed soil was filled into plastic buckets (7kg per bucket) and arranged in five rows. Row A contained the un-amended contaminated soil sample (control), rows B and C contained non-replacement amendments(s) (wood charcoal blocks and sawdust), while rows D and E contained replacement amendment(s) which was/were replaced with fresh ones after every ten experimental days. Laboratory test results conducted on the soil samples at the end of the 40-day experimental period showed a general declined in the THC concentration. It was observed that the THC concentration, in general, declined by about 90% in the remediated contaminated soil samples, as against about 18.71% decline recorded in the control. Furthermore, the contaminated soil samples, with replacement amendments had better results after the experimental period (40 days) with a mean value of 1196 mg kg-1 in THC residuum; when compared with the results from the non-replacement amendments with a mean value of 3269 mg kg-1 THC concentration residual. These results show that charcoal blocks and sawdust significantly degraded the THC concentration in the contaminated soil samples. Data obtained from this study would provide useful information in the utilization of charcoal block and sawdust in bioremediation techniques, for the cleaning up of petroleum products/crude oil contaminated sites.

“…However, these measures often prove insufficient, necessitating the treatment of wastewater. 6 Various treatment methods are available for the removal of water pollutants, but some of these approaches are associated with high costs and limited effectiveness. 7 Conventional techniques employed to eliminate heavy metals from water include chemical precipitation, flotation, flocculation, sedimentation, solvent extraction, oxidation/ reduction, dialysis/electro-dialysis, reverse osmosis, ultra-filtration, electrochemical deposition, ion exchange, and adsorption.…”

Nigerian Bambara Groundnut Shells (BGS) were modified to obtain Raw Bambara Groundnut Shell (RBGS), Carbonized Bambara Groundnut Shell (CBGS) and Bambara Groundnut Shell Lignin (BGSL) and used as bio-adsorbents to remove Lead (Pb), Nickel (Ni) and Cadmium (Cd) ions from industrial wastewater. The adsorption study investigated the effects of bio-adsorbent dosage, wastewater pH and contact time. Preliminary analyses which include: an Atomic Adsorption Spectrophotometer (AAS) on the wastewater and Scanning Electron Microscopy (SEM) were carried out on the different modified BGS, while the mechanism of adsorption was described using adsorption kinetic models. AAS analysis revealed that the concentrations of the heavy metals of interest were above WHO permissible limits in wastewater. SEM analysis revealed that the microspores of the bio-adsorbents were covered after the adsorption process. After the adsorption process, 85 – 91% Pb and 80 – 85% Ni and 92 - 98% Cd were removed by the different bio-adsorbents at optimum conditions of adsorption capacity which occurred at 0.8g dosage, pH of 7 and 120 min contact time. Generally, equilibrium occurred within 90 minutes. The mechanism of Pb, Ni and Cd ions adsorption onto RBGS, CBGS and BGSL bio-adsorbents can be described with diffusion and chemisorption processes. Pseudo-second-order kinetics fitted the adsorption process, implying that it is the rate-controlling step. This study found that the modified Bambara groundnut shell bio-adsorbents can be used as an alternative to conventional adsorbents used to treat industrial wastewater effluent
